WebMolarity (M) is a useful concentration unit for many applications in chemistry. Molarity is defined as the number of moles of solute in exactly 1 liter (1 L) of the solution: M = mol solute L solution Example 3.14 Calculating Molar Concentrations A 355-mL soft drink sample contains 0.133 mol of sucrose (table sugar). WebThe molarity calculator calculates the mass of compound required to achieve a specific molar concentration and volume. To dilute a solution of known molarity, please use the Solution Dilution Calculator. To dilute a solution of concentrated acid or base of known w/w% strength, please use the Acid & Base Molarity Calculator. Formula weight. g/mol. drawing morgan freeman
