What mass of zinc oxide is formed by the interaction of 10 g of zinc with oxygen?

The reaction of zinc with oxygen is described by the following chemical reaction equation:

2Zn + O2 = 2ZnO;

From one mole of zinc, one mole of zinc oxide is formed.

Let’s determine the amount of zinc substance:

N Zn = 10/65 = 0.1538 mol;

The same amount of zinc oxide will be formed.

N ZnO = N Zn = 0.1538 mol;

Let’s find its mass.

m ZnO = 0.1538 x (65 + 16) = 12.4578 grams;
