If half mole of oxygen combine with Al to form Al2O3 , the weight of Al used in the reaction is?

Answers

Answered by Noreen1256

4 Al + 3O2 ---> 2al2o3

3 moles of oxygen react with 108 g of al

1 moles of oxygen react with 108 ÷ 3g of al

And 0.5 mole of oxygen react with 108 × 0.5 ÷ 3g of al

Al = 18 gram

Hope it helps
