WebIts units are mol/L, mol/dm 3, or mol/m 3. Molar concentration, also known as molarity, and can be denoted by the unit M, molar. To prepare 1 L of 0.5 M sodium chloride solution, then, as per the formula, use 29.22 g of sodium chloride (0.5 mol/L * 1L * 58.44 g/mol = 29.22 g). WebJan 3, 2024 · The following equation allows you to find the molarity of a solution: molarity = concentration / molar mass The concentration denotes the mass concentration of the solution, expressed in units of density (usually g/l or g/ml). Molar mass is the mass of 1 mole of the solute. It is expressed in grams per mole.
