Question

What is the volume of a solution containing 2 g mole of sugar that will give rise to an osmotic pressure of 1 atmosphere at STP?

• A. 42.8 litre
• B. 43.8 litre
• C. 34.8 litre
• D. 44.8 litre

Answer 1

The correct option is D 44.8 litre

we have,

$\pi =CRT$

$1=\frac{givenweight}{molecularweight\ast volume}\ast 0.082\ast 273$

$1=\frac{2}{volume}\ast 0.082\ast 273$

$volume=44.77or44.8L$
