How much energy in Btu is required to heat one gallon of liquid carbon tetrachloride at 0 degrees Celsius and 1atm at its boiling point at 1 atm?
Just trying to get through the finals grind.

If you can't figure this one out on your own I have some bad news for you re: thermo 2.

Damn I'm so glad I bitches out and went to CM

3 cups of BTU.

Dude this is a high school chemistry question. It's the sensible heat from 0 deg C up to the boiling point (whatever it is) plus the latent heat of vaporization at 1 atmosphere.
You'll probably get numbers in the table in BTU/lb so you'll need to know the specific gravity to convert gallons to mass.

I got 36,499.627 Btu, but this teacher likes to make life difficult and only answers to the right decimal are correct. This is thermo by the way, and I do have an A for the people who say I won't do well in Cheg thermo.

Unit analysis is your friend. Best advice I've ever gotten non-sexual related

q=mass*specific heat capacity * deltaT
that's the sensible heat
Add in latent heat of vaporization * mass for the heat to vaporize it.
NIST has a database of all the things you need with a little googling. Put it in engineering units and solve away.
