If Cp = 20 J/mol.K then for 1 mole gas we get Cv= _. You can use Cp/Cv = 1.7.
Correct answer: D. 11.7 J/Kmole
- A. 10.6 J/Kmole
- B. 2.7 J/Kmole
- C. 13 J/Kmole
- D. 11.7 J/Kmole
Explanation
Cp/Cv=1.7 and Cp=20, then Cv =20/1.7=11.76 J/Kmole

About Molar Specific Heat of a Gas
Molar specific heat is the heat required to raise the temperature of one mole of a gas by one kelvin, expressed through Q = nCΔT. Questions compare the constant volume value Cv with the constant pressure value Cp, apply the ideal gas relation Cp − Cv = R, and identify how the thermodynamic process affects heat capacity.
