Specific Heats of Gases - Cp, Cv, γ & Mayer's Relation

If cp and cv denote the specific heats (per unit mass of an ideal gas of molecular weight M, then

Show answer and solution

Answer: (c)

Mayer's relation for molar heats: $C_P - C_V = R$ .
Specific heat per unit mass $c = C/M$ , so $c_p - c_v = \dfrac{R}{M}$ .
So the answer is (c) $c_p - c_v = R/M$ .
