Determine the osmotic pressure of a solution prepared by dissolving 25 mg of `K_2SO_4` in 2 litre of water at 25° C, assuming that it is completely dissociated.

Text Solution

Verified by Experts

Mass of solute `(K_(2)SO_(4))` = 25 mg
Mass of solvent = 2 L, i = 3
`pi=iCRT=3xx(25xx10^(-3))/(174)xx1/(2)xx0.083xx298=5.33xx10^(-3)"bar"`
