Question

What ions are present in Al2O3

Answer 1

Answer:

aluminum ions are present in Al2O3

Answer 2

Answer:

Explanation:

Now, 1 mole of Al2O3 contains 2 moles of Al.

The atomic mass of aluminium is given to be 27 u.

This means that 1 mole of aluminium atoms ( or aluminium ions ) has mass of 27 grams , and it contains 6.022 × 10^23 aluminium ions.

Now, 27 g of aluminium has ions = 6.022 × 10^23 aluminium ions.
