Question

1 kg of bituminous coal having 5% Sulphur by mass is completely burnt. Assume that Sulphur is completely converted to SO2. 19% of this SO2 escaped into atmosphere and 75% of escaped SO2, was converted to H, SO. How many grams of H2SO4 is produced in atmosphere.​

Answer 1

Answer:Correct option is

B

4×10

4

Given, a sample of coal contains 1% of sulphur by weight.

Therefore, weight of sulfur in 2×10

6 kg of coal is 2×10

6 × 100

1

=2×10

4 kg.

The reaction is S+O

2 →SO

2 . Weight of sulfur dioxide produced when 2×10

6 kg of coal is burnt will be 2×10

4 × 32

64

=4×10

4 kg.
