Is there a difference between molecules, formula units, and atoms? Aren't they all particles? What is the difference? I don't get how you can tell. How do you differentiate?
What are the 3 different types of molar mass?
Molecules are particles made up of atoms.
Formula units (like moles) are just words you use to count small particles more effectively.
As an example, a "pair" is a unit comprising 2 items.
A mole is a unit that comprises of 6*10^23 items
There's only one kinda molar mass...it refers to the mass of one mole of stuff (any stuff)
Hope I helped
AGH! can't help you here hon! after gr.10 science, I only took bio in gr.11... and I suck a55 in it!! - because my class got a foreign exchange teacher from australia... and she did not know how to teach! - I bombed the course! :P now in gr.12, the only science I'm taking is exercise science! sorry!
try google or sparknotes!
I agree with leevan molecules are particles made up of atoms. Atoms are also invisible particles made up of protons, neutrons and electrons
while looking through element we divide it descendingly by saying first comes the compound then molecule and then the atom...
