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
`Mw=(W)/(PV).RT`
Given ,`W=10 g, P=1.18 atm , V=1 L ,R=0 .0821` , and `T=273 K`.
`Mw = (10)/(1.18xx1)xx0.0821xx273=189.94`
