Part of the SO2 that is introduced into the atmosphere by the combustion of sulfur-containing compounds ends up being converted to sulfuric acid,H2SO4 by the following reaction.

2SO2 + O2 + 2H2O -> 2H2SO4

What is the percent yield of H2SO4 if 100. g of SO2 is completely consumed, producing 100. g of H2SO4 ?
