Answer to Question #148707 in General Chemistry for kokomma

Question

Calculate the maximum mass of iron produced when 1.5kg of Fe2O3 is reduced by excess carbon monoxide. The equation for the reaction is
Fe2O3 + 3CO 2Fe + 3CO2.

Answer 1

Molar mass of Fe₂O₃= (56x2) + (16x3) = 130gmol^-1

Molar mass of Fe= 56gmol^-1

From the balanced equation

130g of Fe₂O₃ produces 2(56)g of Fe

130g of Fe₂O₃ produces 112g of Fe

Therefore, 1500g will produce 112/130x1500

= 1292g of Fe

= 1.29Kg of Fe.
