(\mathrm{R}=0.082)\)

  1. A 4.96atm
  2. B 2.46 atm
  3. C 20.5 atm
  4. D 12.3 atm
Verified Solution

Answer & Solution

Correct Answer

(D) 12.3 atm

Step-by-step Solution

Detailed explanation

For a semimolar solution, Molarity \((M)=0.5\)
\(\pi=\mathrm{MRT}=0.5 \mathrm{~mol} \mathrm{~L}^{-} \times 0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~K}^{-1}\)\(\mathrm{~mol}^{-1} \times 300 \mathrm{~K}=12.3 \mathrm{~atm}\)
