    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
