A 1.000-g sample of impure Al2(CO3)3 (233.991 g/mol) decomposed with HCI according to the equation below; the liberated CO₂ (44.010 g/mol) was collected on calcium oxide and found to weigh 0.0625 g. Calculate the percentage of Al (26.9815 g/mol) in the sample. Al2(CO3)3 + 6HCI → 3CO2 + 3H₂O + 2AlCl3
