Question

R. Calculate the mass of sulfur dioxide
produced by burning 16 g of sulfur in
excess of oxygen in contact process.
(Average atomic mass : S = 32 u,
0 = 16 u)
(Ans. 32 g)
Explain​

Answer 1

Explanation:

S+O2=SO2

SO2= 32+16+16 = 64g

O2= 16+16 = 32g

by chemical equations,

32g S gives 64g SO2

1g S gives (64/32)g SO2

hence, 16g S gives (64/32)×16g SO2= 32g SO2
