Homework Help: Chemistry

Posted by Holly on Tuesday, September 25, 2012 at 1:21am.

Ok so reviewing my notes I also got 11,326.6 as the volume in ml. The density of water he wanted us to use was (0.9975) and I went from 1 gal of H2O = 3.785 liters = 3785 grams then multiplied by 3 giving me 11,355g H2O. The only other step I could come up with was using the molality of solute 15.48 mols/kg x 11.355 kg of solvent and working my way back from grams to gallons of ethylene glycol which gave me 0.260 gal. The computer did not like that answer. I'm a little confused on the g/lbs you mentioned in your previous answer.
