A gas is compressed from 73.7 L to 1.9 L at 0.70 atmospheres? In addition a total of 4400 J of heat are gained from warmer surroundings. What is the change in internal energy in kJ?

I have a general idea of how to do this, but I tried and got -2851.8, which isn't right.

What is the enthalpy change (in kJ) for burning 3.20 g of ethyl alcohol?

I got 94.95 which apparently isn't right.

Please help!
