Chemistry HW! help?
please show me step by step, thanks!
In a blast furnace, iron(III) oxide reacts with coke (carbon) to produce molten iron and carbon monoxide:
Fe2O3 + 3C → 2Fe + 3CO
How many kilograms of iron would be formed from 131 kg of Fe2O3?
??kg

you can do this as a stoichiometry problem
131kg. . . . . . . . . . . .. . 91.6kg (answer)
Fe2O3. . +. . 3C . → . .2Fe. . + . . 3CO
(159.7g/mol). . . . . . .. (55.85g.mol)
0.82mol. . . . . . . . . . . .1.64mol
. . |_______1 to 2________|
or
you can use a mass proportion
m 2Fe / m Fe2O3 = 2(55.85) / 159.7 = X / 131
X = 91.6 kg

131 kg of Fe2O3 X (1 kmole / 159.7 kg) X (2 kmole Fe / 1 kmole Fe2O3) X (55.85 kg Fe / kmole) = 91.63 kg Fe
