Answer: 1.8 moles Fe and 2.7 moles are produced.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
3 moles of require 1 mole of
Thus 2.7 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 3 moles of give = 2 moles of
and 3 moles of
Thus 2.7 moles of will give =
of
and
of
Thus 1.8 moles Fe and 2.7 moles are produced.
