Answer:
2646.13g of Al or 2.65kg of Al
Explanation:
Equation of reaction
2Al₂O₃ → 4Al + 3O₂
From equation of reaction,
2 moles of Al₂O₃ will produce 4 moles of Al
Number of moles = mass / molar mass
Mass = number of moles * molarmass
Molar mass of Al₂O₃ = 101.96g/mol
Mass = 2 * 101.96 = 203.92g
Mass of Al = number of moles (4) * molar mass of Al
Mass = 4 * 26.98
Mass = 107.92g
203.92g of Al₂O₃ = 107.92g of Al
5000g of Al₂O₃ = x g of Al
X = (5000 * 107.92) / 203.92
X = 2646.13g of Al
X = 2.65Kg of Al
