1. Sulfuric acid is called monohydrate, we write down the equations for its production:
S + O2 = SO2;
2SO2 + O2 = 2SO3;
SO3 + H2O = H2SO4;
2.Calculate the chemical quantities:
n (S) = m (S): M (S) = 320: 32 = 10 kmol;
n (S) = n (SO2) = n (SO3) = n (H2SO4) = 10 kmol;
3.Calculate the mass of sulfuric acid:
m (H2SO4) = n (H2SO4) * M (H2SO4);
M (H2SO4) = 2 + 32 + 4 * 16 = 98 g / mol;
m (H2SO4) = 10 * 98 = 980 kg.
Answer: 980 kg.
