Gas Constant, R
Will we ever need to use one of the other gas constants given on the constants/equations sheet for the midterm or only the 8.314 one?

Re: Gas Constant, R
I don't know for sure, but I've used 8.314 J/(molK) for the most part this quarter. However, some practice problems have used the 0.08206 (L*atm)/(molK), so honestly I'd check to see if my units cancel just to be safe. Hope this helps!

Re: Gas Constant, R
I agree, always make sure that you check your units of everything else before deciding what value of R to use.

These values are all equivalent, they are just in different units. Depending on the units of the given information, these other values can be very helpful.

Re: Gas Constant, R
It depends on the formula you use and the units within the formula you use and values you are given.

We often use 0.0821 when calulating with PV = nrT. For the others, it is possible I suppose.
