When making a solution in a lab, there are different ways to express the concentration. Some of the most common ways are listed below: 1. Molarity (M): moles of solute/liters of solution or moles/L (mol/L) 2. w/v (g/mL): weight in grams of solute/milliliters of solute 3. w...
First, you will need to find the number of moles you need for this solution. To do this, you will need to make use of the desired molarity and the volume of desired solution. (1mol1L)(1L)=1mol This calculation means that you need one mole of salt. Now, you need to use the mola...
Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...

We calculate the theoretical yield by taking the given mass of the reactants and multiplying it by the molar mass of the reactants and the molar mass of the products. The unites will cancel out and leave grams in the end. What does the percent yield tell you? The percent yield is the...
Chemists have a variety of means at their disposal to communicate the concentration of chemicals in solution. One common method of describing concentration is to give the moles chemical per liter solution, or the molarity. A mole is a term which stands f
Example 1: To prepare a liter of a simple molar solution from a dry reagent Multiply the formula weight (or MW) by the desired molarity to determine how many grams of reagent to use: Chemical FW = 194.3 g/mole; to make 0.15 M solution use ...
Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. To convert grams to moles, the molar mass ...
