jay_rocks SG heres d qn. 63.0dm³ of carbon monoxie, measured at r.t.p, was ued to react with iron (iii) oxide. what mass of iron was produced at the end of the reaction? the eqn for the reaction is Fe2O3 (s) + 3CO (g)----> 2Fe (s) + 3CO2 (g)
poon cho tang SG no of of moles of CO = 63/24 no of moles of Fe = 2/3 × no of moles of CO = 2/3 × 63/24 = 1.75 moles atomic weight of Fe = 55.8 mass of Fe = 1.75 × 55.8 = 97.6 g
