The chloride in an aqueous sample of $\mathrm{BaCl}_2$ is precipitated with $50.0 \mathrm{~mL}$ of $0.100 \mathrm{M} \mathrm{AgNO}_3$. The excess silver nitrate is titrated with $17.0 \mathrm{~mL}$ of $0.125 \mathrm{M} \mathrm{K}_2 \mathrm{CrO}_4$. Calculate the mass of the barium chloride in the sample.

$$\mathrm{BaCl}_2(a q)+2 \mathrm{AgNO}_3(a q) \rightarrow 2 \mathrm{AgCl}(s)+\mathrm{Ba}\left(\mathrm{NO}_3\right)_2(a q)$$

$$2 \mathrm{AgNO}_3(a q)+\mathrm{K}_2 \mathrm{CrO}_4(a q) \rightarrow \mathrm{Ag}_2 \mathrm{CrO}_4(s)+2 \mathrm{KNO}_3(a q)$$
