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

Options:

Answer:

Solution:

The two solution should have same molar concentration for being isotonic.
Molar concentration of cabe sugar = Molar concentration of urea $= \frac{6}{60} = 0.1 mol/L$
concentration of cane sugar in $g/L$
$= molar concentration \times molecular weight$
$= 0 .1 × 342 = 34 .2$
