Calculating the osmotic pressure at 27^(...

Calculating the osmotic pressure at `27^(@)C` of an aqueous solution containing `4.4 gm` of glucose per `100mL` solution.

Text Solution

Verified by Experts

The correct Answer is:
6
`pi V = (w)/(m)ST`
`V = (100)/(1000) = 0.1 litre, w = 4.4 g`
`T = 27+273=300K, m = 180, pi = ?`
`S = 0.0821 "litre atm" K^(-1) mol^(-1)`
`:. pi = (wST)/(Vm) = (4.4 xx 0.0821 xx 300)/(0.1 xx 180)`
`= 6.020 atm ~~ 6 atm`
