My solutions manual shows the way to solve this problem is by using the equation U=H+nRT, but no value for temperature is given in the problem. The solutions guide uses the value of 298 K for the temperature. Will there ever be an instances on the midterm where we will need to assume standard temperature in order to solve the problem?

I believe that they will include the temperature in the given problem, however, I would still double-check with your TA to make sure.

I think that for most problems, if the information is not give you just have to know the standard conditions and assume these are the values in the problem.
