${\mathrm{K}}_2\mathrm{C}{\mathrm{r}}_2{\mathrm{O}}_7+6\mathrm{F}\mathrm{e}\mathrm{S}{\mathrm{O}}_4+7{\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4\to {\mathrm{K}}_2\mathrm{S}{\mathrm{O}}_4+\mathrm{C}{\mathrm{r}}_2(\mathrm{S}{\mathrm{O}}_4{)}_3+3\mathrm{F}{\mathrm{e}}_2(\mathrm{S}{\mathrm{O}}_4{)}_3+7{\mathrm{H}}_2\mathrm{O}$
For${\mathrm{K}}_2\mathrm{C}{\mathrm{r}}_2{\mathrm{O}}_7,\mathrm{M}=0.1\mathrm{M},{\mathrm{n}}_1=1,{\mathrm{V}}_1=?$
For$\mathrm{F}\mathrm{e}\mathrm{S}{\mathrm{O}}_4,\mathrm{M}=0.5\mathrm{M},{\mathrm{n}}_2=6,{\mathrm{V}}_2=35$ml
$\frac{{\mathrm{M}}_1{\mathrm{V}}_1}{{\mathrm{n}}_1}=\frac{{\mathrm{M}}_2{\mathrm{n}}_2}{{\mathrm{n}}_2}$
${\mathrm{V}}_1=29.2$ml
