Question

Calculate the solubility of Cacl2 in g/L based on the experiement. Given 650g of CaCl2 added to 1.0L and allowed to dissolve as much as possible. While the remaining solid CaCl2 is filtered out of the solution and found to have a mass of 5.509g. What is the solublity of CaCl2

Answer 1

Amt dissolved = 650g-5.509 = ?
?g/L is the solubility. Watch the number of significant figures.
