Problem: Article: Find the concentration of the acid solution on the label, or in the word problem you are working on. This number is often written in units of molarity, or molar concentration, abbreviated as M. For example, a "6M" acid contains six moles of acid molecules per liter. We'll call this starting concentration C1. The formula below will also use the term V1. This is the volume of the acid we will be adding to water. We probably won't use the entire bottle of acid, though, so we don't know what this number is yet. The desired concentration and volume of acid is typically determined by a school assignment or by the requirements of the laboratory you are working in. For example, we might want to dilute our acid to a concentration of 2M, and need 0.5 liters (0.1 US gal). We'll call this desired concentration C2 and the desired volume V2.  If you are using unusual units, convert them all to units of molar concentration (moles per liter) and liters before you continue. If you are not certain what concentration or volume of acid is required, consult your teacher, a chemist, or an expert in the task you plan to use acid in. Whenever you prepare to dilute a solution, you can use the formula C1V1 = C2V2. words, this means "the initial solution's concentration x its volume = the diluted solutions' concentration x its volume." We know this is true because concentration x volume = the total amount of acid, and the total amount of acid will remain the same as it is added to the water. In our example, we can write this formula (6M)(V1)=(2M)(0.5L). This term, V1, will tell us how much of the initial acid solution we need to add to water in order to end up with the desired concentration and volume. Rearrange the formula as V1=(C2V2)/(C1), then plug in the numbers you know. In our example, we would end up with V1=((2M)(0.5L))/(6M)=1⁄6 liter (0.0 US gal). This approximately equals 0.167 liters (0.0 US gal), or 167 milliliters. Now that you now V1, the amount of acid you'll be using, and V2, the amount of solution you'll end up with, you can easily calculate how much water you need to make up the difference. V2 - V1 = the volume of water required. In our case, we want to end up 0.5 liters (0.1 US gal) and will be using 0.167 liters (0.0 US gal) of acid. The amount of water we need = 0.5L - 0.167L = 0.333L, or 333 milliliters.
Summary: Check what you already have. Decide on an end result. Write the formula for calculating dilution. Solve the formula for V1. Calculate how much water you'll need.

INPUT ARTICLE: Article: Line a baking sheet with parchment paper or nonstick aluminum foil. Place the shaped sopes on the lined baking sheet. Cook them in your preheated oven for approximately 10 minutes, or until they feel firm to the touch.  Keep at least 1 inch (2.5 cm) of space in between each sope when you arrange them on the baking sheet. Unlike fried sopes, baked sopes won't gain much color after being cooked through. As long as the sopes are firm, however, they should be ready to use and enjoy. Once the sopes have finished cooking, remove them from the oven and set them aside in a warm area while you prepare the filling. It's a good idea to cover the sopes with a clean, dry kitchen towel to help them hold in more heat.

SUMMARY: Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius). Bake the sopes for 10 minutes. Keep warm.

In one sentence, describe what the following article is about: Place the SD card back in its slot inside the disk tray. Press the "Power" button on the front of the Wii to do so. In order to use the Homebrew Browser, your Wii must be connected to the Internet. You should see this icon on the home page of the Wii. Doing so brings up the Homebrew Channel pop-up window. It's at the bottom of the window. This option is in the top-right corner of the screen. Your Wii's new Homebrew Browser will launch; from this point, you can search for and download things like games and apps as you please. The Homebrew Browser will display several lines of code upon startup. This is normal.
Summary: Insert the SD card back into your Wii. Power on your Wii. Make sure your Wii is connected to the Internet. Select the homebrew channel. Select Start. Select HOMEBREW BROWSER.

In one sentence, describe what the following article is about: Just like eating, thinking is something we need to do to survive, so it is sometimes hard to judge when you are doing too much of it. However, there are several red flags that you are doing too much thinking for your own good. Here are a few of them:  Are you consumed by the same thought over and over again? Are you not making progress by thinking about this particular thing? If so, this may be a sign that you should move on. Have you analyzed the same situation from a million angles? If you've found too many ways to look at something before you decide how to act, you may be being counterproductive. Have you enlisted the help of your twenty closest friends in thinking about a particular thing? If so, then it's time to realize that you can only ask for so many opinions about the same idea before you drive yourself insane. Are people constantly telling you to stop over-thinking things? Do people tease you for brooding, being a philosopher, or staring out of rainy windows all the time? If so, they may have a point. . If you feel like you don't know how to stop thinking, you need to learn what it's like to "let go" of your thoughts, so that it's something you can do deliberately. Imagine that thinking is like breathing; you do it all the time, without even realizing it. But if you need to, you can hold your breath. Meditating will help you learn how to release your thoughts.  Just spending 15-20 minutes meditating every morning can make a dramatic impact on your ability to stay in the present and let go of all of your nagging thoughts. You can also meditate at night to help yourself wind down. Running or even walking vigorously can help you take your mind off of all of those annoying thoughts and to focus on your body. Participating in something particularly active, like power yoga, martial arts or beach volleyball, will have you so focused on your body that you won't have time for your thoughts. Here are some great things to try:  Join a circuit gym. Having to switch to a new machine every minute when you hear that bell ring will keep you from getting lost in your thoughts.  Go hiking. Being around nature and seeing the beauty and stillness around you will keep you more focused on the present moment.  Go swimming. Swimming is such a physical activity that it's even harder to swim and think. Once you've said everything aloud, even if you're talking to yourself, you've begun the process of letting go. Walk around and pace if you have to. Once you've put your ideas out there, you've begun the process of putting them out into the world and out of your thoughts. You can say them aloud to yourself, your cat, or to a trusted friend. . You may have exhausted your own thinking power, but someone else might be able to offer a different perspective that makes the decision clearer. This can help let go of your troubling thoughts. Your friend can make you feel better, can ease your problems, and can also make you realize when you're spending way too much time thinking. Besides, if you're hanging out with a friend, you're not just thinking, right? That's something.
Summary:
Accept that you're thinking too much. Meditate Exercise. Say your ideas out loud. Ask for advice
