Chapter 5, Problem 82(choose chapter or problem)
A solution contains \(Cr^{3+}\) ions and \(Mg^{2+}\) ions. The addition of 1.00 L of 1.51 M NaF solution causes the complete precipitation of these ions as \(CrF_{3}(s)\) and \(MgF_{2}(s)\). The total mass of the precipitate is 49.6 g. Find the mass of \(Cr^{3+}\) in the original solution.
