if the ratio of Cp/Cv for a gas is 1.3 and it's atomic mass is M, the molar mass of the gas will be |
|
Answer» 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 = \(\frac R{C_v\times0.3}\) |
