The number of aluminium ions present in 54 g of aluminium

• GC Atomic Structure

The number of aluminium ions present in 54 g of aluminium (atomic weight 27) is

1. 2
2. 18
3. 1.2 x 10²⁴
4. 1.1 x 10²⁴

Answer

From mole concept, 27 g has 6.022×10²³ ions.

54 g will have 2 x 6.0²²×10²³ = 1.2 x 10²⁴

The correct option is C.
