1) We draw up an equation and put down the coefficients: Fe2O3 + 3H2-> 2Fe + 3H2O
2) According to the formula, we find the amount of substance H2 (amount of substance = volume of gas / molar volume of gas. Molar volume is a constant value equal to 22.4 l / mol). V (H2) = 5.6 (l) /22.4 (l / mol) = 0.25 mol.
3) According to the equation, we get the proportion: 0.25 / 3 = x / 2, hence x = 0.17 mol (Fe).
4) Using the formula, we find the mass of iron (mass = amount of substance * molar mass). m = 0.17mol * 56g / mol = 9.33g.
