Hydrogen sulfide is an impurity in natural gas that must be
removed. One common removal method is called the Claus
process, which relies on the reaction:
8 H2S1g2 + 4 O21g2¡S81l2 + 8 H2O1g2
Under optimal conditions the Claus process gives 98% yield of S8
from H2S. If you started with 30.0 g of H2S and 50.0 g of O2, how
many grams of S8 would be produced, assuming 98% yield?
