Answer to Question #197322 in Chemistry for Emma

Question

How many grams of aluminum oxide are  produced from the synthesis reaction of 30.0 g of Al 
 balance the equation  
_ Al+ _ O2 -> _ Al2O3

Answer 1

Solution:

Balanced chemical equation:

4Al + 3O₂ → 2Al₂O₃

According to the equation:

(30.0 g Al) × (1 mol Al / 26.98 g Al) × (2 mol Al₂O₃ / 4 mol Al) × (101.96 g Al₂O₃ / 1 mol Al₂O₃) = 56.68 g

Mass of Al₂O₃ = 56.68 g = 56.7 g Al₂O₃

Answer: 56.7 grams of aluminum oxide (Al₂O₃) are produced.
