It depends on what values are given or what values you can find based on what is given= 0.08206 L*atm(K^-1)(mol^-1) versus 8.314 J(K^-1)(mol^-1). Notice that the units for each are different, so you use one if you are given (or can find) L and atm and the other if you are given (or can find) J.

Yes, as mentioned above depending on the question and what is being asked we would be able to differentiate when to use either or value for R. It is important to remember the units because this will help us distinguish which one to use.
