When doing problems where they ask for the amount of molecules of an element or compound, do you still use avogadro's number to convert between molecules and moles or can it only be used for atoms?

You can use Avogadro's number to convert between molecules and moles.

Yes, you use Avogadro's number :)

Avogadro's number isn't just limited to just atoms or molecules, but you can even describe 6.0221 x 10^23 cups as a mole of cups. Avogadro's number can be used for anything!

Yes! You would use Avogadro's number to find the number of molecules in a given amount of a compound if you know the number of moles of the compound. The number for Avogadro's number that our textbook uses is 6.0221 x 10^23. So for every mol of a compound, there are 6.0221 x 10^23 molecules. The concept of moles isn't just limited to atoms, it applies to molecules as well! Hope this helped!

Yes you would use Avogrado's constant.

you would use avagadro's number for both molecules and atoms
