Question

The osmotic pressure of solution at 0°C is 16 atm,
what will be its osmotic pressure at 546 Kunder
similar conditions?

Answer 1

Answer:

Osmotic pressure is denoted by π.

Formula: π = C*R*T , where, C is the concentration in molality, R is the gas constant, T is the temperature.

1st case

π1 = C*R*273. [0°C = 273 K]

=> 16 = C*R*273 ...........(eq1)

2nd case

π2 = C*R*546. ..........(eq2)

Comparing eq1 and eq2

π2/16 = (C*R*546)/(C*R*273)

=> π2 = 16 *2

=> π2 = 32 atm.

So the answer is 32 atm.

π1 is the initial osmotic pressure,

π2 is the final osmotic pressure.

Another thing to note is that, similar conditions in the question refer to same concentration (C) being used.
