When a fuel that contains sulfur is burned,the sulfur is converted to SO2. Suppose all of this SO2 is then oxidized in the atmosphere to SO3. The SO3 dissolves in atmospheric moisture to form sulfuric acid (H2SO4) contributing to acid rain. A particular fuel contains 1% sulfur. How much atmospheric H2SO4 could be formed by burning 11.4 tons of this fuel?

Question

Answer in units of tons.

Answer 1

S + O2 ==> SO2
2SO2 + O2 ==> 2SO3
SO3 + H2O ==> H2SO4

1 mol S = 1 mol SO2 = 1 mol SO3 = 1 mol H2SO4.
S0 11.4 tons of fuel, if all 1% is converted to H2SO4. would be 11.4 x 0.01 = ? tons.

Answer 2

Thanks!
