My chemistry is a bit rusty, so I'd like to see if I can get confirmation of a calculation.

I'm trying to figure out the number of ethane molecules in a molecule of ethylene glycol.

Here's what I've looked at so far:

ethylene glycol = ethylene oxide + water
OHCH2CH2OH = CH2CH2O + H2O

2 ethylene oxide = 2 ethylene + oxygen
2 CH2CH2O = 2 CH2CH2 + O2

So,
2 ethylene glycol = 2 ethylene + oxygen + 2 water
2 OHCH2CH2OH = 2 CH2CH2 + 02 + 2 H20

I'm not sure about the process of converting ethane to ethylene.  If the process uses one ethane molecule to make one ethylene molecule, then I get a 1:1 ratio of ethane molecules to ethylene glycol molecules.  Is that correct?

Thanks much!
