Question

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, 1.64 atm, 2.46 atm, 4.10 atm, 2.05 atm

MARKS App · Accepted Answer

π 1 V 1 + π 2 V 2 = π R (V 1 +V 2 ) 164 × 1 + 2.46 × 1 = π R × 2 π R = 4.10 2 = 2.05 atm Here, π R = Osmotic pressure of resulting solution.
