Question

What will be the concentration of sucrose solution which develops an osmotic pressure of 2 atm at 27°C?

Answer 1

The concentration of the sucrose solution is approximately 0.0812 mol/L.

Answer 2

The osmotic pressure ($\pi$) is calculated using the formula $\pi = CRT$. Given $\pi = 2$ atm, T = 27°C = 300 K, and using R = 0.0821 L atm/mol K, the concentration C is found by rearranging the formula to $C = \frac{\pi}{RT}$. Substituting the values gives $C = \frac{2}{(0.0821)(300)} = \frac{2}{24.63} \approx 0.0812$ mol/L.
