- A 402
- B 292
- C 302
- D 312
Answer & Solution
Correct Answer
(A) 402
Step-by-step Solution
Detailed explanation
Mass of one mol gas, \(\mathrm{m}=22.4 \times 10^{-3} \mathrm{~kg}\) Specific heat ratio, \(\mathrm{r}=1.6\) Pressure at STP, \(\mathrm{P}=1.01 \times 10^5 \mathrm{~N} / \mathrm{m}^2\) Volume at STP, V \(=22.4 \times 10^{-3} \mathrm{~L}\) Speed of sound is given as…
