In a thermite reaction, iron(III) oxide reacts with aluminium to produce molten iron and aluminium oxide. The ratio of the masses of iron(III) oxide and aluminium that react is:
iron(III) oxide:aluminium=80:27 \text{iron(III) oxide} : \text{aluminium} = 80 : 27 iron(III) oxide:aluminium=80:27Calculate the mass of iron(III) oxide that reacts with 135 g of aluminium.
