Question

How much aluminum can be retrieved from 55.6 g of aluminum oxide, Al2O3?

Answer 1

Answer :

approx 30g of alluminium metal

Explanation:

moles of allumina = 55.6g/101.96g mol^-1 = 0.545 . mol

given that each mole of alumina contains 2 moles of alluminium metal ,there are

1.09.mol × 26.98.g mol^-1 = 29.408 approximately 30g of alluminium metal.
