For the unbalanced reaction: FeSO4
(s) → Fe
2O3
(s) + SO2
(g) + O2
(g) ; how many total moles
of gas are produced from the decomposition of 9.98 mol FeSO4
(s)?

• Chemistry -

Balance the equation first.
4FeSO4(s) ==> 2Fe2O3(s) + 4SO2(g) + O2(g)
9.98mols FeSO4 x [(5 mols SO2+O2)/4 mols FeSO4] = 9.98 x 5/4 = ?
