Molarity is equal to number of moles divided by volume in liters. So to find the number of moles, multiply the volume by the molarity.

Use the formula M=n/L and manipulate the equation to where the number of moles equals the molarity times the volume.

As a side note, if you are given grams. You can just divide grams by the element's molar mass to find moles if you are trying to find Molarity or Volume.
