Question

how many moles of iron can be made from Fe2o3 by the use of 16 mole of carbon monoxide in the following reaction

Answer 1

Fe2O3 + 3 CO = 2Fe + 3 CO2

Multiply the equation by 16/3

16/3 Fe2O3 + 16 CO = 32/3 Fe + 16 CO2

5.33 Fe2O3 + 16 CO = 10.66 Fe + 16 CO2

So,

5.33 moles of Fe2O3 and 16 moles of CO will give 10.66 moles of Fe and 16 moles of CO2
