If you had 9.65 x 1026 atoms of Ag, how many moles would you have?

1602.99 moles

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 atoms. This implies that 1 mole of Ag also contains 6.02x10^23 atoms.

Now, if 1 mole of Ag contains 6.02x10^23 atoms,

therefore, Xmol of Ag will contain 9.65x10^26 atoms i.e

Xmol of Ag = 9.65x10^26/6.02x10^23

Xmol of Ag = 1602.99 moles

Therefore, 1602.99 moles of Ag contains 9.65x10^26 atoms

b.

the accuracy of the data.
