A sample of zinc oxide contains 80.25% zinc. Calculate the equivalent mass of zinc.

We can use oxide method to calculate equivalent mass :

Equivalent mass = $\frac{Mass of metal \times 8}{Mass of oxygen in oxide }$
Mass of oxygen in oxide = 100 - 80.25 = 19.75 

$\frac{80.25 \times 8}{19.75}$ = 32.50 g
