We know that,
Cpm - Cvm = R
where,
Cpm = molar heat capacity at constant pressure
Cvm = molar heat capacity at constant volume
As we know,
Cv.m = M.Cv
where, m = molar mass of gas
∴ MCp - MCv = R
Cp - Cv = R/M
Cp/Cv - 1 = \(\frac R{C_v.M}\)
⇒ 1.3 - 1 = \(\frac R{C_v.M}\)
⇒ 0.3 = \(\frac R{C_v.M}\)
⇒ M = \(\frac R{C_v\times0.3}\)
