[H+]=0.1× propto =10- 2 ∴ propto =0.1 π= iCRT =1.1 × 0.1 × 0.082 × 300=2.7 atm

Q. $pH$ of $0 .1 M$ aqueous solution of weak monoprotic acid $HA$ is $2 .$ Calculate osmotic pressure of this solution at $27^{o} C .$ Take solution constant $R = 0 .082 L atm/K-mol$

2.46 atm

3.5 atm

3.05 atm

2.7 atm

$[H^{+}] = 0.1 \times \propto= 1 0^{- 2}$

$∴ \propto= 0.1$

$π = i CRT = 1.1 \times 0.1 \times 0.082 \times 300 = 2.7 a t m$

Q. pH of 0.1M aqueous solution of weak monoprotic acid HA is 2. Calculate osmotic pressure of this solution at 27oC. Take solution constant R=0.082Latm/K-mol
