Question

For 2Al + 3Cl₂ → 2AlCl₃, if 0.3 mol Al and 0.4 mol Cl₂ are mixed, how much AlCl₃ forms?
  1. A
    0.267 mol
    Correct
  2. B
    0.3 mol
  3. C
    0.4 mol
  4. D
    0.2 mol

Correct answer

0.267 mol

Explanation

Al needs: 0.3 × (3/2) = 0.45 mol Cl₂, but only 0.4 mol available → Cl₂ limits. AlCl₃ from Cl₂: 0.4 × (2/3) = 0.267 mol.
