Suppose a thin sheet of zinc containing 0.2 mol of the metal is completely converted in air to zinc oxide (zno) in one month. how would you express the rate of conversion of the zinc?

Molecular mass of Zn = 65.38

1 mol = 65 g

0.2 mol of Zinc = 13.076 g of Zinc

13.076 g of Zinc is completely converted in air to ZnO in one month

= 13.076 g / 30 days = 0.435 g per day

The rate of conversion of the zinc = 0.44 g / day
