Question

9. 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
(c) 0.60 mol/L
(d) 0.45 mol​

Answer 1

Answer:

Solution :- Option A is correct

Nacl should lie isotonic with

blood

π

blood

=C

Nacl

RT×i

7.8=C×0.0821×310×2

C=0.153mole

−1

The concentration of on

aqueous Nacl solution that

is used in blood stream

is 0.15 mol/L
