A `10%` solution of urea is isotonic with `20%` solution of `'x'` at same temperature. Calculate molecular weight of `x`.

Explanation

Given `10%` solution of urea is isotonic with `20%` solution `x`
`pi_("urea")=pi_(x)`
Asked Molecular weight of `x(M)=?`
Formulae: `pi_("urea")=pi_(x)`
`C_(1)RT=C_(2)RT`
Explanation : `C_(1)=` concentration of urea solution, `C_(2)=` concentration of `x` solution
`(10)/(60)xx(1000)/(100)xxRT=(1000)/(100)xxRT`
`m=0.0213`
