(CP/CV) = (5/2 R/3/2 R) = (5/3) = 1.67

Q. Equal volumes of two monoatomic gases, $A$ and $B$ , at same temperature and pressure are mixed. The ratio of specific heats $(C_{p} / C_{v})$ of the mixture will be:

0.83

1.50

3.3

1.67

$\frac{C _{P}}{C _{V}} = \frac{5/2 R}{3/2 R} = \frac{5}{3} = 1.67$
