simple molecular formula question
« on: October 10, 2012, 10:54:19 PM »
I am given 80.34 % carbon and 19.66% hydrogen.  I got the empircal formula of CH4 with 15.04g.

Now, I must find the molecular formula:

At standard conditions, 250 mL of the compound has a mass of 0.358 g.

Where do I begin?
Thanks for your time!
