Please answer question 19 Part A

A solution contains \( \text{Cr}^{3+} \) and \( \text{Mg}^{2+} \). The addition of 1.00 L of 1.53 M NaF solution is required to cause the complete precipitation of these ions as \( \text{CrF}_3 (s) \) and \( \text{MgF}_2 (s) \). The total mass of the precipitate is 49.8 g. You may want to reference (Pages 331 - 336) Section 8.5 while completing this problem. **Part A** Find the mass of \( \text{Cr}^{3+} \) in the original solution. \[ m = \, \underline{\hspace{2cm}} \, \text{g} \]
