The osmotic presssure of a solution containing 50g sucrose per litre of solution at `27^@C` is 3.65 atmosphere. Calculate the value of R.

Text Solution

Verified by Experts

Mass of sucrose dissolved per `dm^3=50g`
Molar mass of sucrose =342 g
`n=50g//342 g mol^(-1)`
`piV=nRT`
`R=(pi V)/(n T)=(3.65 atm xx " 342 g mol"^(-1) xx 1 dm^3)/(50 g xx 300K)`
