Question

Which of these solutions has the maximum osmotic pressure at a given temperature $\text{T}$?

• A. $100\text{mL}$ of $\text{1 M}$ urea solution
• B. $300\text{mL}$ of $\text{1 M}$ glucose solution
• C. A mixture of $100\text{mL}$ of $\text{1 M}$ urea solution and $300\text{mL}$ of $\text{1 M}$ glucose solution
• D. All of these are isotonic

Answer 1

The correct option is D All of these are isotonic

All solution have the same number of particles i.e n = 1 and also have the same value of $\pi$
$n_1=n_2$
${\pi }_1={\pi }_2$ (isotonic)
