Question

A solution is prepared by dissolving 96.4 g of RbI in enough water to form 865 mL of solution. Calculate the mass % of the solution if the density of the solution is 1.06 g/mL. A) 12.7% B) 11.3% C) 9.4% D) 10.5% E) 11.9%

Answer 1

Mass of the Rbi = 96.4 g Volume of the solution = 865 Ml Mass of the solution = 1.06 8/ mL times 865 mL = 917 g Mass percent of Rbi = 96.4 g/917 g times 100 = 10.5 Hence, the mass percent of Rbi is 10.5
