You need to dissolve CaCl2 in water to make a mixture that is 31.5% calcium chloride by mass

[From: ] [author: ] [Date: 11-11-15] [Hit: ]
1 g x .685 % H2O= 318.......
If the total mass of the mixture is 465.1g, what masses of CaCl2 and water should be used?

a) Mass of CaCl2 in grams?
b)Mass of water in grams?
10+ for the best explanation! Thanks.

465.1 g x 0.315 % CaCl2= 146.5 g CaCl2
465.1 g - 146.5 g CaCl2= 318.6 g H2O (or 465.1 g x .685 % H2O= 318.6 g H2O)
