heyA!
here is your answer...
The molar mass of gold = 196.97 g
Number of atoms = given mass / molar mass × 6.022 x 1023 atoms
⇒39.4 g /196.97 g × 6.022 x 1023 atoms = 1.2 × 10^23 atoms of gold.

Answer : The number of atoms of gold recovered are .
Solution : Given,
Mass of gold = 39.4 Kg = (1Kg = 1000g)
Molar mass of gold = 197 g/mole
First we have to calculate the moles of gold.
As, 1 mole contains atoms
contains atoms
Therefore, the number of atoms of gold recovered are .
