moles of
Al

)
3
contain
14.0
mol Al atoms,
21.0
mol S atoms, and
84.0
mol O atoms.
Explanation:
In one mole of aluminum sulfate,
Al
2
(SO
4
)
3
, there are 2 moles Al atoms, 3 moles sulfur atoms, and 12 moles O atoms.
To determine the number of moles of atoms of each element in 7.00 moles of the compound, multiply the number of moles times 7.00.
