Yo thanks for taking the advice.
Here it is
at normal pressure and tempurature
helium is 22.4 moles per liter.
Helium has a mass of 4 grams per mole.
In other words a 1 liter ballon has (4 divided by 22.4) grams of helium in it.
The metric system is so much easier!

You can probably find most of what you're looking for on this page:
http://en.wikipedia.org/wiki/Helium
It's got the molecular mass, melting point, boiling point, density, heat capacity, electron configuration, and more.
