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 0.208 % . What mass of a 0.208 % KCN solution contains 914 mg of KCN ? Express the mass to three significant figures and include the appropriate units.

The mass of the solution will be 4,394 mg

Mass percent

The mass percent of a component in a solution can be derived as follows:

Mass percent = mass of component/total mass of solution x 100%

In this case, the mass percent of KCN in the solution is 0.208 and the mass of KCN is 914 mg.

The mass of the 0.208% KCN solution will be:

                           914/0.208 = 4,394 mg
