If `6gm` of `CH_(3)COOH` is dissoved in benzene to make `1` litre at `300K`. Osmotic pressure of solution is found to be `1.64` atm. If it is known that `CH_(3)COOH` in benzene forms a dimer. Calculate degree of association of acetic acid in benzene?

Explanation

`i=1+((1)/(n)-1)beta`
`1.64=0.0821xx300xx[1+((1)/(n)-1)beta]xx0.1`
`rArr 1.64=0.0821xx300[1-(beta)/(2)]0.1`
`(1.64)/(00.821xx30)=(2-beta)/(2)`
`(1.64)/(2.46)=(2-beta)/(2) 4=6.3beta`
`beta=(2)/(3)`
