What is osmotic pressure of a semi molar solution at \(27^{7} \mathrm{C} ?
(\mathrm{R}=0.082)\)
- A 4.96atm
- B 2.46 atm
- C 20.5 atm
- D 12.3 atm
Answer & Solution
Correct Answer
(D) 12.3 atm
Step-by-step Solution
Detailed explanation
For a semimolar solution, Molarity \((M)=0.5\)
\(\pi=\mathrm{MRT}=0.5 \mathrm{~mol} \mathrm{~L}^{-} \times 0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~K}^{-1}\)\(\mathrm{~mol}^{-1} \times 300 \mathrm{~K}=12.3 \mathrm{~atm}\)
\(\pi=\mathrm{MRT}=0.5 \mathrm{~mol} \mathrm{~L}^{-} \times 0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~K}^{-1}\)\(\mathrm{~mol}^{-1} \times 300 \mathrm{~K}=12.3 \mathrm{~atm}\)
