Molar Mass: The Mass of Atoms!

Next time: Converting between Grams and Moles!
Molar mass is the mass in grams of one mole of a substance. It can be determined using the atomic mass on the periodic table. Molar mass is measured in g/mol.
If we refer to our periodic table, we see that the molar mass of Beryllium is 9.0.


  Molar Mass of Compounds
To determine the molar mass of a compound add the mass of all the atoms together. It really is as simple as that!

 For extra practice:



 And for a great way to end class Mr. Doktor showed us what would happen if you heated hydrogen gas. It went something like this:
