i think it depends on which constants you use like if you use R = 0.08206 L atm/K mol then you use atm but they also give you R = 62.364 L Torr/K mol on the equation sheet
Most of the time, they are provided on the constants and equations sheet. You can check the sheet on his website to see if it is on there. Usually the one on his website reflects what is given to us during the tests & midterms.
There is a conversion to go from L*atm to Joules on the equation sheet, so when calculating work, you should try and get to atm in order to make the conversion to Joules. The constants/equations sheet is super helpful to look at before the test to know what you will be working with.
While the conversion for units of pressure were not included on the last test, four different values for the gas constant (R) were provided: one includes joules, one includes atm, one includes bar, and one includes Torr. So, if your calculation involves the ideal gas law at all, chances are any pressure units will cancel out.
