A solution of CaCl2 in water forms a mixture that is 29.0 % calcium chloride by mass. If the total mass of the mixture is 263.8 g, what masses of CaCl2 and water were used?
Homework Answers
% mass = (mass of CaCl2 / total mass) x 100
% mass = 29.0 %
mass of solution = 263.8 g
mass of CaCl2 = ?
29.0 = (mass of CaCl2 / 263.8) x 100
mass of CaCl2 / 263.8 = 0.29
mass of CaCl2 = 76.5 g

You are given a 1.25 gram mixture of calcium nitrate and calcium chloride. You dissolve this mixture in 200 mL of water and add an excess of 0.300 M silver nitrate. You collect and dry the white precipitate which forms and find it has a mass of 0.405 grams. Calculate the percent calcium chloride by mass in the original mixture.
