An aqueous solution of glucose containing 60 g glucose `(C_(6)H_(12)O_(6))` per litre has an osmotic pressure of 5.2 bar at 300 K. The concentration of the glucose solution having osmotic pressure 0of 1.3 bar at the same temperature is :

A

`1/10M`

B

`1/5M`

C

`/220M`

D

`1/12M`

Text Solution

Verified by Experts

The correct Answer is:
e
Osmotic pressure `(pi)alphaM`
`pi_(1)/pi_(2)=M_(1)/M_(2)` (for the same solution at the same temperature)
`(5.2)/(1.3)=(1/3)/M_(2)or M_(2)=1/3xx1/4=1/12M`
