Question

A student makes a solution for analysis by mixing 5.86 grams of Cu2SO4 into 283.2 grams of water. The density of water at the temperature of the lab at the time the solution was made is 0.9926 g/mL. Calculate the molarity, molality, mole fraction, and mass percent of the copper I sulfate. • The molarity of the solution is: 0.09 * • The molality of the solution is: 0.09 * • The mole fraction of the solution is: 0.001269* • The mass percent of the solution is: 2.03
