0.0036g of NH4+ x 1mol of NH4+/18.04g of NH4+ x 6.02*10^23 electrons of NH4+/1mol of NH4+
= 1.20 x 10^20 electrons of NH4+
Answer: 0.30 M
Explanation:

According to the neutralization law,
where,
= molarity of
solution = ?
= volume of
solution = 24.6 ml
= molarity of
solution = 0.222 M
= volume of
solution = 33.0 ml
= valency of
= 21
= valency of
= 1
Therefore, the molarity of the HCI solution is 0.30 M
Elements always exist as pair of atoms called molecules .
Explanation:-
- The material which has only one types of similar atoms called element .
- Ex:-Sodium,Carbon etc
