### Avogadro's Number

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.

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

Yes, use Avogadro's Number (6.022x10^23) to convert between molecules and moles.

What is the difference between a molecule and an atom?

In regard to Lily Smith's question, an atom is the most basic unit of the element. A molecule is when different atoms are bonded together. For example, look at a water molecule. It is made up of hydrogen and oxygen atoms.
