Q.
A solution of glucose $(C_{6}H_{12}O_{6})$ is isotonic with $4\, g$ of urea $(NH_{2}-CO-NH_{2})$ per litre of solution. The concentration
of glucose is:
Solutions
Solution:
Isotonic solution has same conc
$\pi_{1}=\pi_{2}\,C_{1}=C_{2}\,n_{1} = n_{2}$
$\frac{W_{1}}{M_{1}}=\frac{W_{2}}{M_{2}}$
So, $\frac{x}{180}=\frac{4}{60}$
$\Rightarrow x=12\,g$
