Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Cp-Cv =nR where n is the no. of moles In this question there is no information about weight. So we consider their weights are equal. n=w/M where M is the molecular weight. Now you put the values and you will get the result. I hope now the question is clear to you. For any doubt comment me.
where did Cp - Cv = nR comes from? it was just 'R' right.?
sayan complete formula is nR. Once again visit the proof
