53.576g of MgSO4.2H2O are dissolved in 250.00mL of 1.50 M Ba(NO3)2 solution to produce barium sulfate precipitate. Barium sulfate formed 80.0 g after the reaction. Assume that the solution volume is constant and calculate the following concentrations.
a) What is the concentration of magnesium nitrate in solution, and the concentration of nitrate ion in solution?
