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 0.173 %. What mass of a 0.173 % KCN solution contains 779 mg of KCN

450. g of 0.173 % KCN solution contains 779 mg of KCN.

Explanation:

Mass of the solution = m

Mass of the KCN in solution = 779 mg

Mass by mass percentage of KCN solution = 0.173%

1 mg = 0.001 g

m = 450,289 mg × 0.001 g = 450.289 mg ≈ 450. g

450. g of 0.173 % KCN solution contains 779 mg of KCN.
