108.0 gm of silver = 1 atom of silver.
21.6 gm of silver = 21.6/108 =0.02.
21.6 gm of silver = 21.6/108 =0.02.

Answer is A: As moles of silver (21.6/108) = 0.2 and moles of water is also (1.8/18) = 0.1.
So H2O Dissociates into [H+] and [OH-]. So it has two hydrogen ion that can accept an electron [H+] and one that can donate an electron [OH-] when Ag is in its ionic form i.e. Ag+.

Moles of silver = 0.2.
Atoms of silver = 1.2044*10 raise to the power 23.
Moles of water = 0.110.
Atoms = 1.088*10 raise to the power 23.
Correct answer is (A).
Atoms of silver = 1.2044*10 raise to the power 23.
Moles of water = 0.110.
Atoms = 1.088*10 raise to the power 23.
Correct answer is (A).

Why Atoms of Silver = 1.2044*10 raise to the power 23.
Atoms of Water = 1.088*10 raise to the power 23.
Can you please explain?

@Divya.
Atoms of silver = Given no. of moles*6.023x10^23.
= 0.2*6.023x10^23.
= 1.2044x10^23.
Atoms of silver = Given no. of moles*6.023x10^23.
= 0.2*6.023x10^23.
= 1.2044x10^23.
