The average osmotic pressure of human blood is 7.8 bar at `37^@C`. What is the concentration of an aqueous NaCl solution that could be used in the blood stream?

A

0.16 mol/L

B

0.32 mol/L

C

0.60 mol/L

D

0.45 mol/L

Text Solution

Verified by Experts

The correct Answer is:
B
`pi=CRT`
`C=(pi)/(RT)=(7.8)/(0.082xx310)=0.31`mol/L.
