Let N be the number of atoms and n be the number of moles, these quantities are related by the Avogadro's number:

$N\approx6.02*10^(23)mol^(-1)\cdot n$

Thus,

$N\approx6.02*10^(23)mol^(-1)\cdot3.6mol=21.672*10^(23)=2.1672*10^(24)\approx2.17*10^(24)$

So, there are approximately 2.17 x 10²⁴ atom, which corresponds to alternative B.
