How many Aluminum are in Al2O3?
A
3
B
2
C
5
D
None of the above
Explanation: 

Detailed explanation-1: -2 o 3 now find the number of moles of aluminium of aluminium that will be equal to in 1 mole. We have 2 moles of aluminium, or we can say that 1 molecule of a l, 2 o 3 contains 2 atoms of aluminium.

Detailed explanation-2: -One Al2O3 A l 2 O 3 molecule has two aluminium atoms.

Detailed explanation-3: -Finally we have a balanced equation: 4Al + 3O2–> 2Al2O3 . There 4 aluminums on each side and 6 oxygens on each side!

Detailed explanation-4: -The mole ratio of Al to Al2O3 is 4:2. Use this mole ratio for the stoichiometry conversion.

Detailed explanation-5: -Answer: The percentage of Al in Al2O3 is 52.94%.
