Ideal Gas and Real Gas

Q.

$\frac{{\mathrm{C}}_{\mathrm{p}}}{{\mathrm{C}}_{\mathrm{v}}}=\frac{5}{3}$two moles of an ideal gas are mixed with three moles of another ideal gas$\frac{{\mathrm{C}}_{\mathrm{p}}}{{\mathrm{C}}_{\mathrm{v}}}=\frac{4}{3}$. $\frac{{\mathrm{C}}_{\mathrm{p}}}{{\mathrm{C}}_{\mathrm{v}}}$for the mixture is?

1. $1.47$

2. $1.4$

3. $1.42$

4. $1.50$
