the moles of copper is 8.093 x10^10 moles
<u><em>calculation</em></u>
The moles of copper is calculated using the Avogadro's constant.
That is According to Avogadro's law
1 mole = 6.02 x 10^23 atoms
? moles = 4.872 x10^34 atoms
by cross multiplication
=[( 1 mole x 4.872 x10^34 atoms) / 6.02 x10^23 atoms]
= 8.093 x10^10 moles
