Question

zinc react with O2 as
2ZnS+3O2 .........>2ZnO +SO2
what volume of O2 at S.T.P is required to react with 194g of ZnS?​

Answer 1

Answer:

The mole Number of ZnS is 194/97=2 mole

Hence 2 mole of ZnS reacts with 3 mole of O2.

In STP volume of 1 mole O2 gas is 22.4 L

In STP volume of 3 mole O2 gas is 22.4×3 L= 67.2 L
