2. A solution contains non-volatile solute of molecular mass
Mp . Whih of the following can be used to calculate molecular mass of the solute in terms of osmotic pressure (m = Mass of solute, V = Volume of solution and π = Osmotic pressure)
a. Mp = (m/ π ) VRT
b. Mp = (m/ V ) RT/π
c. Mp = (m/ V ) π/ RT
d. Mp = (m/ V ) πRT
Ans. b
Explantion : π = n/V RT ⇒ Mp = (m/ V ) RT/π
