FREE Expert Solution

We are being asked to calculate the molarity of a solution prepared by dissolving 12.5 g of Na2CrO4 in enough water to produce a solution with a volume of 750 mL .


Recall that molarity is given by

molarity = moles of soluteLiters of 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
