During the Pandemic you love to cook sunny side up egg. To your curiosity you want to know how many moles are there in 3.01 x 10²³ molecules of table salt (NaCl) you put on the egg you cooked.

Answer 1

When talking about NaCl (or other such salts) we usually refer to formula units instead of molecules, but since your question states "molecules" I will use that term.

We simply need to use Avogadro's number to convert "molecules" to moles:

3.01x1023 molecules x 1 mole / 6.02x10²³ molecules = 0.500x10²³ molecules = 5.00x10²² molecules
