You can practice converting between the mass of a solution and mass of solute when the mass percent concentration of a solution is known. The concentration of the KCN solution given in Part A corresponds to a mass percent of 0.410 %. What mass of a 0.410 % KCN solution contains 616 mg of KCN? Express the mass to three significant figures and include the appropriate units. View Available Hint(s) mass = Value Units
