How many grams of CaCl, are needed to make 728.4 g of a solution that is 40.0% (m/m) calcium chloride in water? Note that mass is not technically the same thing as weight, but (m/m) has the same meaning as (w/w). mass: g CaCl, How many grams of water are needed to make this solution? g H,0 mass: What is the volume percent, % (v/v), of an alcohol solution made by dissolving 135 mL of isopropyl alcohol in 757 mL of water? Assume that volumes are additive. % (v/v) volume percent: The mass of solute per 100 mL of solution is abbreviated as % (m/v). The abbreviation % (w/v) is also common.
