Three moles of an ideal monatomic gas are at a temperature of 345 K. Then, 2114 J of heat are added to the gas, and 811 J of work are done on it. What is the final temperature of the gas?

2. Relevant equations

3. The attempt at a solution

I have a feeling I'm missing an equation. I thought the equation was U = Q - W but that won't help me here.
