q, w, and DU

A gas is allowed to expand at constant temperature from a volume of 2.00 L to 11.20 L against an external pressure of 1.500 atm. If the gas loses 256 J of heat to the surroundings, what are the values of q, w, and DU? Pay careful attention to units.

a. -256 J, +838 J, +1094 J
b. +256 J, -1398 J, -1142 J
c. -256 J, -1398 J, -1654 J
d. +256 J, +1398 J, +1654 J
e. -256 J, -419 J, -547 J
