​ If a monoatomic gas of 1 mol (γ = ​5/3) is mixed with 1 mol of diatomic gas

Question

If a monoatomic gas of 1 mol (γ = \(\frac { 5 }{ 3 } \)) is mixed with 1 mol of diatomic gas (γ = \(\frac { 7 }{ 5 } \)), then determine the value of γ for the mixture (where γ = C_P/C_V).

Answer 1

If the ratio of specific heats for the mixture is γ, then
