In the reaction 2 Al + 3 Cl₂ → 2 AlCl₃, if 0.50 mol of aluminium reacts with excess chlorine, calculate the mass of aluminium trichloride produced.

Step-by-step solution

1. Mole ratio gives 0.50 mol Al produces 0.50 mol AlCl₃.
2. Calculate molar mass of AlCl₃: $26.98+3\times 35.45=133.33$ g mol⁻¹.
