Question

A 5% solution of cane sugar is isotonic with 1% solution of substance xd the molecular weight of x is

Answer 1

$\mathfrak{The\:Answer\:is}$

Molar conc. of cane sugar solution :

$\qquad= \large\frac{5}{342} \times \frac{1000}{100}=\frac{50}{342}$

Molar conc. of solution $X= \large\frac{l}{m}\times \frac{1000}{100}$

$\qquad= \frac{10}{m}$

$\large\frac{10}{m} =\frac{50}{342}$ or

$m= 68.4$
