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).

All options are incorrect because Any option does not show the same number of moles like silver= 21.6/108= 0.2 moles.

As we know quantities having equal no.of moles have equal no.of particles(atoms, ions molecules).

No of atoms = moles * Avogadro no.

So, Option A is correct.

The Same value we also have for c2h5oH.
4.6/46 = 0.1.

so, I am confused in A and D. to Please anyone explain in detail.

Avagadro theory state the no of atoms with the mole of a gas. We can not use that theory on liquid and solid. Right?
