Question

Calculate the osmotic pressure of a 0.204 M aqueous solution of sucrose, C12H22O11, at 37

Answer 1

It will be

(0.204 M)(0.0821 L-atm/mol-K)(310 K) = 5.19 atm ans

Answer 2

π = CRT

where, π = osmotic pressure

R = 0.0821, constant to give pressure in atm

T = Temperature in K

C = concentration of the solution

so,

π = 0.204*0.0821*310

π = 5.19 atm

Answer 3

Osmotic pressure is a colligative property and is defined as OP = M*R*T
M is molarity. R is the gas constant. T is the temperature in Kelvin.

OP = (0.204 M)(0.0821 L-atm/mol-K)(310 K) = 2=5.19 atm
