Question

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

• A. $4.48$ lit
• B. $0.448$ lit
• C. $44.8$ lit
• D. $448$ lit

Answer 1

The correct option is C $44.8$ lit

$molarity=\frac{w}{M.\omega t}\times \frac{1}{V\left(lit\right)}=\frac{n}{V}$

here $n=2$

at STP means $T=298K$

$\sqcap =MRT$

$1=\frac{2}{V\left(lit\right)}\times 0.0821\times 298$

$V=48.9$ liter

Option C is correct.
