किसी (0.1,M) विलयन का परासरण दाब (300,K) पर (3.69,atm) है। \(R=0.082,L,atm,K^{-1},mol^{-1}\) होने पर विलेय का (i) क्या है?
A (0.1,M) solution has osmotic pressure (3.69,atm) at (300,K). If \(R=0.082,L,atm,K^{-1},mol^{-1}\), what is (i) for the solute?

B. (1.5)
Concept
\(\pi=iCRT\) से \(i=\frac{\pi}{CRT}\)। / From \(\pi=iCRT\), \(i=\frac{\pi}{CRT}\).
Why this answer is correct
\(i=\frac{3.69}{0.1\times0.082\times300}=1.5\)। / \(i=\frac{3.69}{0.1\times0.082\times300}=1.5\).
Exam Tip
परासरण दाब से (i) निकालते समय सांद्रता मोलरता में होनी चाहिए। / While finding (i) from osmotic pressure, concentration should be in molarity.
