What mass of aluminum carbide can be obtained by calcining carbon with 10.8 g of aluminum?

Carbon calcination reaction:
3C + 4Al = Al4C3.
1) Find the molar mass of aluminum according to the periodic table: 27.
2) Find the amount of aluminum substance. To do this, divide the mass of aluminum by its molar mass: 10.8 / 27 = 0.4 mol.
3) According to the reaction equation, there is one mole of aluminum carbide for four moles of aluminum. This means that the amount of aluminum carbide substance is: 4 * 0.4 = 1.6 mol.
4) Molar mass of aluminum carbide: 4 * 27 + 12 * 3 = 144.
5) Find the mass of aluminum carbide: 144 * 1.6 = 230.4g – the answer.
