A nitric acid solution is labelled 6.0% W/W nitric acid by mass. What mass, in kg, of pure solute is in 1.84 kg of nitric acid? To determine how much calcium chloride has been used, you take a sample of slush from the road to analyze. You collect the following data: Mass of empty container: 54.54 g Mass of container and sample of slush: 160.65 g Then, you evaporate the water from the solution and determine the mass of the residue to be 3.87 g. What is the percent by mass of CaCl2 in the slush that was collected?
