The molarity of a solution that contains 5.85 g of NaCl in 2.0 L of solution is ________.

Question

Quizplus · Accepted Answer

The molarity (M) of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. The molar mass of NaCl is approximately 58.5 g/mol. Therefore, 5.85 g of NaCl is equivalent to 0.1 moles (5.85 g / 58.5 g/mol). When these 0.1 moles are dissolved in 2.0 L of solution, the molarity is 0.1 moles / 2.0 L = 0.050 M.
