SOLVED:In a laboratory experiment, a 15.0 -mL sample of KCl solution is poured into an evaporating dish with a mass of 24.10 g. The combined mass of the evaporating dish and KCI solution is 41.50 g . After heating, the evaporating dish and dry KCl have a combined mass of 28.28 g .(9.4) a. What is the mass percent (m / m) of the KCl solution? b. What is the molarity (M) of the KCl solution? c. If water is added to 10.0 mL of the initial KCl solution to give a final volume of 60.0 mL, what is the
