Aluminum oxide is decomposed to extract pure aluminum from the mineral. If 6.7 tons of aluminum oxide is mined, calculate the mass of pure aluminum produced?
Al2O3 when only Al is wanted, you get 3.618 tons.
1 mole of aluminum oxide has a molecular weight of 102 grams (Al=27 grams and O=16 grams). It means that for 1000 kg of compound you can get 529 kilograms of aluminum (in pure quality). The ratio is
For 6.7 tons it means
