  1. A \(40536\)
  2. B \(40537\)
  3. C \(40535\)
  4. D \(40538\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(40535\)

Step-by-step Solution

Detailed explanation

\(\because \pi= CRT\) \(\pi=\frac{n}{V} R T\) \(\pi=\frac{\omega}{V} \frac{R T}{M}\) \(M=\frac{\omega R T}{\pi \times V}\) \(M=\frac{0.63 \times 0.083 \times 300}{1.29 \times 10^{-3} \times 300 \times 10^{-3}}\) \(M=40535\,gm / moL\)
