Calculate the temperature of 0.05 M sucrose solution in Kelvin if the osmotic pressure of the solution is 1.5 atm. [ R = 0.0821 dm 3 atm K K − 1 mol − 1 ]

Question

TestHub · Accepted Answer

The osmotic pressure of a solution is given by the formula:

$π = CRT$

Substituting the given values $π = 1.5 atm$ , $C = 0.05 M$ , and $R = 0.0821 dm^{3} atm K^{- 1} mol^{- 1}$ :

$1.5 = 0.05 \times 0.0821 \times T$

$T = \frac{1.5}{0.05 \times 0.0821}$

$T = \frac{1.5}{0.004105}$

$T = 365.4 K$

Answer: $365.4$
