Problem: Describe how you would prepare 2.00 L of 0.100 M K2CrO4 from solid K2CrO4.

FREE Expert Solution

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.
