For chemical reactions that take place in solution the chemist needs to express the amount of material (solute)  in a given amount of dissolving material (solvent). Generally, concentration is the ratio of the amount of solute  to amount of solvent. There are several ways to express concentration. We will examine the most common ones  used in chemistry. Molarity Molarity is define as the number of moles of solute per liter of solvent. What is the Molarity of a solution prepared by dissolving 8.0 grams of  NaOH  in  H 2 O  so that the final  volume is 250 ml? First convert grams to moles: Then calculate the molarity Mass Percent Another way to express concentration is using Mass Percent.
