What is the molarity of a solution prepared by dissolving 47 g of KCl in enough water to give 375 mL of solution?
Molar Mass(KCl) = 74.55 g/mol

Question

Quizplus · Accepted Answer

To find the molarity, divide the number of moles of solute by the volume of the solution in liters. Moles of KCl = 47 g / 74.55 g/mol = 0.6305 mol. Volume in liters = 375 mL / 1000 = 0.375 L. Molarity = 0.6305 mol / 0.375 L = 1.68 M.
