HELP ASAP WILL MARK BRAINLIEST: How many grams of aluminum can be extracted from 5000g of alumina
Lesechka [4]

The grams of aluminium extracted from 5000g of alumina is 2647 grams

<h3>Chemical formula of alumina:</h3>
  • Al₂O₃

Let's calculate the molecular mass of Al₂O₃

Al₂O₃ = 27 × 2 + 16 × 3 = 54 + 48 = 102 g/mol

Therefore,

102 g of Al₂O₃ = 54 g of aluminium  

5000g of Al₂O₃  = ?

mass of aluminium produced = 5000 × 54 / 102

mass of aluminium produced = 270000 / 102

mass of aluminium produced  = 2647.05882353

mass of aluminium produced  = 2647 grams
