What is the molarity of a solution which contains 85.00 g of sodium nitrate dissolved in 2.00 L of solution?
A)0.500 M
B)1.00 M
C)2.00 M
D)4.00 M

Question

Quizplus · Accepted Answer

The molarity (M) is calculated by dividing the number of moles of solute by the volume of the solution in liters. The molar mass of sodium nitrate (NaNO3) is approximately 85 g/mol. Therefore, 85.00 g of NaNO3 is about 1 mole. Dividing by the volume of the solution (2.00 L) gives a molarity of 0.500 M.
