I converted the density to g/l. Molarity to Mass Percent 1. Once the number of grams of solute per liter is known, the molarity can be calculated: Molarity = g of solute/GMW of solute x 1 liter. This is a very important step and the amount of solution is not given but you need to have a specific quantity to do the calculations and one liter is the best assumption for this problem. (a) 0.274 M (b) 2.74 M (c) 3.04 M (d) 4.33 M (e) The density of the solution is needed to solve the problem. [(% x d) / MW] x 10 = Molarity Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight). A 0.332 m aqueous NHCI (MM = 53.49 (density = 1.026 g/mL). X = 8.50 g/L. You can calculate the volume you need to add if you acid is 100 percent pure by relationship density is equal to mass divided by volume. Molarity to molality converter.
