# Problem: Iron(III) oxide reacts with carbon monoxide according to the equation:Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2 (g)A reaction mixture initially contains 22.55 g Fe2O3 and 14.00 g CO.Once the reaction has occurred as completely as possible, what mass (in g) of the excess reactant remains?

###### FREE Expert Solution

The reaction is:

Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g)

Molar masses:

Fe2O3(s) = 159.69 g/mol

CO(g) = 28.01 g/mol

Fe(s) = 55.85 g/mol
