Osmotic pressure of 40% (W/V) urea solution is 1.64 atm and that of 3.42% (W/V) cane sugar is 2.46 atm. When equal volumes of the above two solutions are mixed, the osmotic pressure of resulting solution is

Options:

Answer:

Solution:

$π_{1} V_{1} + π_{2} V_{2} = π_{R} {(V}_{1} {+V}_{2})$
$164 \times 1 + 2.46 \times 1 = π_{R} \times 2$
$π_{R} = \frac{4.10}{2}$
$= 2.05 atm$
Here, $π_{R} =$ Osmotic pressure of resulting solution.
