Question

What is the osmotic pressure of an aqueous solution containing in mol 500 cm3 dissolved 0.2 mol of potassium chloride (completely dissociated) and 2 g of glucose at 37 ° C?

Answer 1

Osmotic pressure $\pi$ can be calculated as

$\pi = CRT$

Here, $i = 1$ because $KCl$ completely dissociates.
