How many silver (ag) atoms are in a silver bar that is 20.0 g? a. 1.3 3 1027 ag atoms b. 6.02 3 1023 ag atoms c. 1.1 3 1023 ag atoms d. 1.8 3 1023 ag atoms

The correct option is, (C)

Explanation: Given,

Mass of Ag = 20 g

Molar mass of Ag = 108 g/mole

First we have to calculate the moles of Ag.

Now we have to calculate the number of atoms in Ag.

As, 1 mole of Ag contains number of Ag atoms

So, 0.185 mole of Ag contains number of Ag atoms

Therefore, the number of atoms present in Ag are,
