If a $6.84 \% (wt./vol.)$ solution of cane sugar $(mol. wt. 342)$ is isotonic with a $1.52 \% (wt./vol.)$ solution of thiocarbamide,then the molecular weight of thiocarbamide is:

Calculate the osmotic pressure of a $0.2 \ M$ aqueous solution of an electrolyte at $300 \ K$. If the van't Hoff factor is $1.6$,find the osmotic pressure. $\left[R=0.0821 \ atm \ dm^3 \ K^{-1} \ mol^{-1}\right]$ (in $atm$)

$A$ $0.6 \%$ solution of urea (molecular mass $= 60$) would be isotonic with
