Question

The osmotic pressure of 5% (mass-volume)solution of cane sugar at 150°C (mol. mass of sugar = 342) is (A) 4 atm (B) 5.07 atm (C) 3.55 atm (D) 2.45 atm

5 % (mass-volume) solution means 5 g of sugar dissolved in 100 mL water. π=(n/V) R T=(5/342) × (1000/100) × 0.0821 × 423 =5.07 atm

Q. The osmotic pressure of 5% (mass-volume)solution of cane sugar at 150 $^{\circ}$ C (mol. mass of sugar = 342) is

4 atm

5.07 atm

3.55 atm

2.45 atm

$5%$ (mass-volume) solution means $5 g$ of sugar dissolved in $100 m L$ water.
$π = \frac{n}{V} RT = \frac{5}{342} \times \frac{1000}{100} \times 0.0821 \times 423$
$= 5.07 a t m$
