In a laboratory experiment, a 15.0 mL sample of a KCl solution is poured into an evaporating dish with a mass of 24.10 g. The combined mass of the evaporating dish and KCl solution is 41.50 g. After heating the evaporating dish and the dry KCl have a combined mass of 28.28 g. 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 five a final volume of 60.0 mL, what is the molarity of the diluted KCl solution?
