the number of moles in 4.61*10^17 atoms of radon

Answer 1

To find the number of moles in 4.61*10^17 atoms of radon, we need to use Avogadro's number, which is 6.022 x 10^23 mol^-1.

First, we need to convert the number of atoms to moles by dividing by Avogadro's number:

4.61 x 10^17 atoms / (6.022 x 10^23 atoms/mol) = 7.667 x 10^-7 mol

Therefore, there are approximately 7.667 x 10^-7 moles in 4.61*10^17 atoms of radon.
