Question

Osmotic pressure of a solution containing 0.1 mole of solute per litre at 273K is (in atm)

• A. $\frac{0.1}{1}\times 0.08205\times 273$
• B. $0.1\times 1\times 0.08205\times 273$
• C. $\frac{1}{0.1}\times 0.08205\times 273$
• D. $\frac{0.1}{1}\times \frac{273}{0.08205}$

Answer 1

The correct option is A $\frac{0.1}{1}\times 0.08205\times 273$

Osmotic pressure ,$\pi =CRT=\frac{n}{V}RT=\frac{0.1}{1}\times 0.08205\times 273atm$
