The osmotic pressure of 5% (mass/volume)...

The osmotic pressure of 5% (mass/volume) solution of cane sugar at `150^@C` (molecular weight of sugar = 342) is

A

4 atm

B

5.07 atm

C

3.55 atm

D

2.45 atm

Text Solution

Verified by Experts

The correct Answer is:
B
5% (mass-volume) solution means 5 g of sugar dissolved in 100 mL water.
`pi = n/V RT = 5/342 xx 1000/100 xx 0.0821xx423 = 5.07` atm.
