Sulfuric acid (H2SO4) is prepared commercially from elemental sulfur using the contact
process. In a typical sequence of reactions,
the sulfur is ﬁrst burned:
S + O2 → SO2 ,
then it is converted to SO3 using a catalyst:
2 SO2 + O2 → 2 SO3 .
The resulting SO3 is reacted with water to
produce the desired product:
SO3 + H2O → H2SO4 .
How much sulfuric acid could be prepared
from 37 moles of sulfur?
