We are being asked to calculate the molarity of a solution prepared by dissolving 12.5 g of Na_{2}CrO_{4} in enough water to produce a solution with a volume of 750 mL .

Recall that molarity is given by

$\overline{){\mathbf{molarity}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{moles}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solute}}{\mathbf{Liters}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solution}}}$

We are going to do the following steps:

Step 1: Determine the moles of solute

Step 2: Determine the Liters of solution

Step 3: Determine the molarity of the solution

Calculate the molarity of a solution prepared by dissolving 12.5 g of Na_{2}CrO_{4} in enough water to produce a solution with a volume of 750. mL .
