Answer:
Step-by-step explanation:
The number of moles can be calculated by dividing the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol).
So, for 8 x 10^23 molecules of sodium, the number of moles would be:
8 x 10^23 molecules / 6.022 x 10^23 molecules/mol = 1.331 moles.
Therefore, there are 1.331 moles in 8 x 10^23 molecules of sodium.
