of
Na.​

Answer 1

Answer:

Explanation:

I am assuming that since you asked this question, that you are familiar with Avogadro’s Constant a useful tool to help us convert from number of moles to number of atoms.

Considering this, we can use the fact that the number of particles = #moles * N A (Avogadro number). Rearranging this we get

#moles = #particles/N a  

#moles =  3.01∗1022/6.02∗1023  

Therefore #moles = 5 * 10^-2

Which simplifies to 1/25 of a mole.
