The concentration in `g//L` of a solution of cane sugar (Molecular weight = 342) which is isotonic with a solution containing 6 g of urea (Molecular weight = 60) per litre is

Answer

`34.2 g L^(-1)`

Explanation

Let wt. of sugar = w g per litre .
`(w xx R xx T)/(342 xx 1) = (6)/(60) xx (RT)/(1)`
` w= 34.2` g/litre.
