The solution containing `10 g` of an organic compound per litre showed an osmotic pressure of `1.18 atm` at `0^(@)C`. Calculate the molecular mass of the compound "(R=0.0821 litre atm per degree per mol)"

Text Solution

Verified by Experts

Applying the equation,
`m =(w)/(PV).ST`
Given, `w=10g,P=1.18 "atm",V=1 "litre",S=0.0821 and T=273K`
`m=(10)/(1.18xx1)xx0.0821xx273=189.94`.
