Ive read that we need to use 3/2 R and 5/2R with the formulas of Cp/v*ln(T2/T1) but I am not getting the right answers . is R not 8.3145? or do I need to divide the entire thing by 2?

I don't have my homework on me right now but on thing I messed up on was using the wrong R, check your units and make sure everything cancels and you get the correct units. Different R's have different units
