An aquesous solution of urea [6%w/v] is isotonic with NaCI solution then mass-volume percentage (%w/v) of NaCI solution then mass- volume precentage (%w/v) of NaCI solution will be :-

A

`1.46%`

B

`5.85%`

C

`2.92%`

D

`11.7%`

Text Solution

Verified by Experts

The correct Answer is:
C
`pi_(1)=pi_(2)`
`:.i_(1)c_(1)=i_(2)c_(2)`
`1xx(6)/(60)xx10=2xx(w)/(58.5)xx10`
`:.W=(58.5)(20)=2.925g`
