Question

Calculate the osmotic pressure of 10% solution of cane sugar in atmosphere at $69^{o}C$ is

• A. 724 atm
• B. 824 atm
• C. 8.21 atm
• D. 7.21 atm

Answer 1

Answer: (C)

$\pi =\text{CST}$

$\pi =\frac{w}{m}\frac{RT}{V}=\frac{10}{342}\times \frac{0.0821\times (273+69)}{0.1}$

$\therefore \pi =8.21\text{atm}$
