Answer:

#1.1*10^-47# moles

Explanation:

To solve this question you have to use Avogadro's constant which states that one mole of any element contains #6.022*10^23# atoms.

In the given example there are #6.3*10^-24# atoms, so the number of moles is:

#(6.3*10^-24 color(red)(cancel(color(black) "atoms"))) / (6.022*10^23 color(red)(cancel(color(black) "atoms"))/"mol") = 1.1*10^-47 "mol"#
