The molarity (M) of a solution is equal to the:

A) number of grams of solute/liter of solvent

B) number of grams of solute/liter of a solution

C) number of moles of solute/liter of solvent

D) number of moles of solute/liter of solution

The correct answer is D) number of moles of solute/liter of solution

Explanation:

Molarity is a measure of concentration and is defined as the moles of solute in 1 liter of solution. Example: 3M NaCl solution (means that there are 3 moles of solute, in this case NaCl, in 1 L of solution)
