${\mathrm{Z}}_2{\mathrm{O}}_3+3{\mathrm{H}}_2\to 2\mathrm{Z}+3{\mathrm{H}}_2\mathrm{O}$

Valency of metal in${\mathrm{Z}}_2{\mathrm{O}}_3=3$

$\text{0}\text{.1596 g}$of${\text{Z}}_{\text{2}}{\text{O}}_{\text{3}}$react with$\text{6 mg}$of${\text{H}}_{\text{2}}$

So 1 g of${\mathrm{H}}_2$react with$=\frac{0.1596}{0.006}=26.6$g of${\mathrm{Z}}_2{\mathrm{O}}_3$

So Eq. wt. of${\mathrm{Z}}_2{\mathrm{O}}_3=26.6$

Now, Eq. wt. of$\mathrm{Z}+$Eq. wt. of$\mathrm{O}=$Eq. wt. of$\mathrm{Z}+8=26.6$

So Eq. wt. of$\mathrm{Z}=26.6-8=18.6$

So At. wt. of$\mathrm{Z}=18.6\times 3=55.8$
