(B)1g Ag(S)
(C)1g Au(S)
(D)1g Zu(S)​

Answer 1

Answer:

$\green{sorry}$

Answer 2

Answer:

(A)1g Cu(S) is the correct answer

Explanation:

Lower the molecular mass, highest the number of atoms

$\boxed{\text{Number of atoms} \propto \dfrac{1}{\text{Molecular weight}}}$

Mass of Cu = 63.5; Ag = 108, Au = 197; Zn = 65

So, Smaller mass is of Cu. Hence Cu is the answer
