Essay

In a metallurgical process the mineral pyrite,FeS2,is roasted in air:
FeS2 + O2 \to Fe2O3 + SO2
The SO2 is then converted into H2SO4 in the following reactions:
2SO2 + O2 \to 2SO3
SO3 + H2SO4 \to H2S2O7
H2S2O7 + H2O \to 2H2SO4
Assuming the mineral is 24.0% FeS2 and the remainder is inert,what mass of H2SO4 is produced if 155 g of the mineral is used?
