What is the molarity of a solution prepared by dissolving 36.0 g of NaOH in enough water to make 1.50 L of solution?
A)0.600 M
B)0.0240 M
C)0.900 M
D)1.35 M
E)0.0428 M

Quizplus · Accepted Answer

The molar mass of NaOH is approximately 40.0 g/mol. Therefore, 36.0 g of NaOH is 36.0 g / 40.0 g/mol = 0.900 mol. Molarity is moles of solute per liter of solution, so 0.900 mol / 1.50 L = 0.600 M.
