What is the molarity of a solution when 15.0 g of NaCl is dissolved to a final volume of 500. mL with water?

Question

Quizplus · Accepted Answer

The molarity (M) of a solution is calculated using the formula M = moles of solute / liters of solution. The molar mass of NaCl is approximately 58.44 g/mol. Thus, 15.0 g of NaCl is equivalent to 15.0 g / 58.44 g/mol = 0.2566 mol. The volume of the solution is 500 mL or 0.500 L. Therefore, the molarity is 0.2566 mol / 0.500 L = 0.513 M.
