WHAT IS THE NUMBER OF MOLES OF ALUMINIUM OXIDE FORMED WHEN 6.75g OF ALUMINIUMIS MADE TO REACT WITH 8g OF OXYGEN.IS I/8MOLE THE RIGHT ANSWER?

1. The reaction for the formation of Aluminium Oxide is as follows:

      4 Al + 3 O2  2 Al2O3

4 moles of Aluminium reacts with 3 moles of Oxygen to give 2 moles of Aluminium Oxide.

2. Number of moles of Al = 6.7526.98=0.25 moles
Number of moles of O2832=0.25
Here Oxygen is the limiting reagent.

3. 0.25 moles of O2 reacts give 23×0.25 = 0.16

So, 18 is not correct.
