(Average atomic mass: S = 32 u, O = 16 u).

पर्याय

• 32

• 64

• 128

• 160

Answer 1

The mass of sulphur dioxide produced by burning 32 g of sulphur in excess of oxygen in contact process is 64 g.

Explanation:

32 g of sulphur combine with 32 g oxygen to form 64 g of sulphur dioxide as follows:

\[\ce{\underset{32 g}{Sulphur} + \underset{32 g}{Oxygen} -> \underset{64 g}{Sulphur dioxide}}\]
