In one sentence, describe what the following article is about: Molarity expresses the relationship between the number of moles of a solute per liters of solution, or the volume of that solution. In formula form, molarity is expressed as: molarity = moles of solute / liters of solution Example problem: What is the molarity of a solution made by dissolving 3.4 g of KMnO4 in 5.2 liters of water? Finding molarity demands that you have the number of moles and the number of liters. If you are not provided with the number of moles but you do have the volume and mass of the solution, you will need to use these two figures to calculate the number of moles before continuing on. Example problem:  Mass = 3.4 g KMnO4  Volume = 5.2 L To calculate the number of moles from the mass or grams of solute used, you must first determine the molar mass of the solute. This can be done by adding together the separate molar masses of each element found in the solution. Find the molar mass of each element using the periodic table of elements. Make sure that you count the atoms for each element and calculate the molar mass of each of the atoms. Example problem:  Molar mass of K = 39.1 g Molar mass of Mn = 54.9 g Molar mass of O = 16.0 g (The solute contains 4 O atoms, so count the 16g 4 times.) Total molar mass = K + Mn + O + O + O + O = 39.1 + 54.9 + 16 + 16 + 16 + 16 = 158.0 g Now that you have the molar mass of the solute, you need to multiply the number of grams of solute in the solution by a conversion factor of 1 mole over the formula weight (molar mass) of the solute. This will give you the number of moles of the solute for this equation.  Example problem: grams of solute * (1/molar mass of solute) = 3.4 g * (1 mol / 158 g) = 0.0215 mol The grams units of the solute and solute mass cancel each other out so you are left with mol units. Now that you have the number of moles, you can divide this value by the number of liters of solution in order to find the molarity. Example problem: molarity = moles of solute / liters of solution = 0.0215 mol / 5.2 L = 0.004134615 You should round off the number of digits after the decimal point to the place requested by your instructor. Usually, this will be two or three places after the decimal point. Additionally, when you write out the answer, abbreviate “molarity” with “M” and state the solute involved. Example problem: 0.004 M KMnO4
Summary: Know the basic formula for calculating molarity. Examine the problem. Find the molar mass of the solute. Convert the grams into moles. Divide the number of moles by the number of liters. Write your answer.

In one sentence, describe what the following article is about: This can be a great way to demonstrate that you were committed to advancing yourself professionally. Even if you have a degree, don't be afraid to take a class in a subject you've previously studied, as a refresher course. Colleges also often provide a wide variety of resources to students that can be valuable tools for finding employment.   Take a seminar. An academic seminar is an intense course of study related to a specific field. In business, "seminar" often refers to a commercial training event. Both can be useful in addressing an employment gap. For example, a teacher might take a class on pedagogy. For example, a software engineer might take a class on a new programming language. Many people choose to do work as a contractor, or to work as a consultant on projects, in between long-term jobs. This can be a great way to develop skills related to your career, as well as provide some income. Consider consulting or contracting. This can be a way to show that even though you were unemployed, you were still working in a sense. Some people are fortunate enough to be able to volunteer regularly, and this is not likely to count against them. Instead, volunteering, especially if it can be connected to your career, will likely look good on your resume. Many organizations hold professional conferences around the country every year. These professional conferences are often great ways to develop professionally. They can also be a wonderful way to network with people in your field.
Summary: Take a class related to your career. Consult or take contract assignments. Volunteer in your community or for a large organization. Attend professional conferences.

In one sentence, describe what the following article is about: " Place the bales onto the pallet on their sides with the cut side up. Line them up evenly, side by side, until you fully cover the pallet with a single layer of bales. If stacked properly, the strings will be on the sides, rather than the top and bottom. This allows for better air circulation. When a bale is on its side, the hay stems should run vertically. The top of the bale will feel sharp and jagged. " The second layer needs to be placed perpendicularly to the first, with all the bales placed width-wise. This time, the strings will be on the top and bottom rather than on the side. You can usually put them loosely in their spot and kick them firmly into place, especially if it's a tight spot. You can also shove the bale in with your knee, which would be safer. Make sure the bales are packed in as tightly as possible.  Tightly packing the bales helps prevent unstable stacks. The orientation of the bales (cut side up) allows for circulation.  If your bales are still green, pack them in a little more loosely. Alternating the direction allows for good air circulation and results in very stable stacks. Changing the direction each time locks the bales in together, almost like puzzle pieces, with great stability. This is the simplest and easiest way to stack hay. Vertically, the bales will form four-bale columns, and between these columns, the stack can collapse. If your stacks are four bales or fewer, this won't be as much of an issue. Cover the pallet with the first layer, then start building stacks from the corners toward the middle. Make sure to keep the corners or each new stack perfectly lined up with the corners below to assure stability.
Summary:
Stack the bottom layer "cut side up. Stack the second layer "top side up. Tuck your bales tightly together. Continue alternating the direction for each layer. Do four layers total for the most stability. Fill the pallet to capacity.
