How can using moles be useful in doing calculations in stoichiometry? Give at least two reasons. In this unit you have been reminded that the mole is...

Stoichiometry is the study of ratios
of elements or compounds and the way they react
with each other in specific
ratios or quantities.  Oftentimes, moles are used in describing
these
releationships between elements and/or compounds.  Moles are useful because they
describe
the number of a specific element required to react with a specific
number of another element. 
Consider the formation of water:

2H2  +  O2  --->  2H20

There are 2 moles of
hydrogen required to react with one mole of oxygen which
