Molarity of a solution is defined as the number of moles, or for ionic compounds such as NaCl, gram formula masses, of solute contained in exactly 1 liter of solution. The gram formula mass of NaCl is 58.44, and 725 mL is 0.725 liter. The molarity is therefore [(23.1/58.44)/0.725] or 0.545, to the justified number of significant digits.
