Calculate the number of grams of solution necessary to provide the following:
a. 68.5 g of sodium chloride from a 12.0% sodium chloride solution

The density of manganese is 7.21 g/mL, that of calcium chloride is 2.15 g/mL, and that of sodium
acetate is 1.528 g/mL. The three solids were placed in a liquid, in which they do not dissolve. The liquid
has a density of 2.15 g/mL. Which solid will sink to the bottom, which will stay on the top, and which
will stay in the middle of the liquid?
