Molarity =
Concentration is the amount of solute dissolved in a certain amount of solution:
amount of solute
concentration of a solution
amount of solution
Solution concentrations are usually given as one of the following:
• Mass percent (m/m)-the mass of the solute in grams for exactly 100 g of solution
• Volume percent (v/v)–the volume of solute in exactly 100 mL of solution
Mass/volume percent (m/v)-the mass of solute in grams for exactly 100 mL of solution
Molarity (M)-the number of moles of solute in exactly 1 L of solution
