Question

in this reaction , 2Al+ 3/2O2 = Al2O3, 9grams of Al will react with how much O2

Answer 1

2moles of Al reacts with 3/2 moles of O2

1mole of Al = 27g
hence, 2moles of Al= 2×27= 54g

1mole of O2 = 32g
hence, 3/2 mole of O2 = 48g

so....

as per question....
54g of Al reacts with 48g of O2
so .. 9g of Al will react with 48×9/54
which is 8g...

so ... 9g of Al reacts with 8g of O2...


hope it helps you......
