1. The problem statement, all variables and given/known data
For some gas specific heats for constant pressure and constant volume are calculated. Universal gas constant is R. Find the formula the helps identify the gas. Include only constants and given information.
2. Relevant equations
3. The attempt at a solution

Molar specific heat at constant volume is $Q=C_vnRT$ and for constant pressure is $Q=C_pnRT$. Is there anything i can use to find that which can help me identify the gas? And what that might be?

Cv and Cp are different for different gases. Do you have specific values? Otherwise I don't see how to proceed apart from "look it up in a table and hope to identify the gas".
