Calculations involving masses

In another experiment, 324 mg of silver is deposited at the negative electrode.

Calculate the number of silver atoms in 324 mg of silver.

Give your answer to 3 significant figures.

( $Ar(Ag)=108\text{relative atomic mass } A_r(\text{Ag}) = 108$ ; Avogadro constant = 6.02 × 10²³ per mole)
