But atom and molecule are not the same. Does this only apply for gas that # of atom and molecules are the same?

Think of what a dozen is... a dozen is a number... 12. Are there units on a dozen? No. You could have a dozen pencils, a dozen muffins, a dozen cats, a dozen atoms, a dozen molecules. In the same way, you could have a mole of atoms, a mole of molecules, etc. A gas could be a molecule so 1 mol of a gas has 6x10^23 molecules. An element consists of atoms so 1 mol of an element has 6x10^23 atoms. Upvote 0 Downvote
