Solution
To convert molecules to moles, you use Avogadro's number, which is 6.02 x 10^23 molecules/mole.
Given that you have 8.23 x 10^27 molecules of NaCl, you can use the following conversion:
(8.23 x 10^27 molecules) * (1 mole/6.02 x 10^23 molecules)
When you perform this calculation, you get approximately 1.37 x 10^4 moles of NaCl.
So, the correct answer is 1.37 x 10^4 moles.
