Surely you've got a Periodic Table in front of you if you are doing your physics or chemistry homework?


#He# is a monatomic molecule with a molar mass of #4.003*g*mol^-1#. You should have a Table in front of you; you will be permitted to use one in every test in Chemistry or Physics you ever sit.
