Recall that molarity is the ratio of the moles of solute and volume of solution in liters.
Solutions are usually prepared in volumetric flasks, which is calibrated at a certain volume.
First, we need to determine the mass of K2CrO4 needed to be dissolved. The molar mass of K2CrO4 is 2(39.10 g/mol K) + 52.00 g/mol Cr + 4(16.00 g/mol O) = 194.20 g/mol.
Describe how you would prepare 2.00 L of 0.100 M K2CrO4 from solid K2CrO4.
