WebJun 9, 2024 · Mass Percent. When the solute in a solution is a solid, a convenient way to express the concentration is a mass percent (mass/mass), which is the grams of solute per 100g of solution. Percent by mass = mass of solute mass of solution × 100%. Suppose that a solution was prepared by dissolving 25.0g of sugar into 100g of water. WebMay 6, 2024 · You can calculate the concentration of a solution following a dilution by applying this equation: M i V i = M f V f where M is molarity, V is volume, and the subscripts i and f refer to the initial and final values. Example: How many milliliters of 5.5 M NaOH are needed to prepare 300 mL of 1.2 M NaOH? Solution: 5.5 M x V 1 = 1.2 M x 0.3 L
