Nacl should lie isotonic with blood π text blood = C text Nacl RT × i 7.8= C × 0.0821 × 310 × 2 C =0.153 mole -1 The concentration of on aqueous Nacl solution that is used in blood stream is 0.15 mol / L

Q. The average osmotic pressure of human blood is $7.8$ bar at $3 7^{\circ} C$ . What is the concentration of an aqueous $N a Cl$ solution that could be used in the blood stream?

0.15 mol/L

0.30 mol/L

0.45 mol/L

0.60 mol/L

Nacl should lie isotonic with
blood
$π_{blood} = C_{Nacl} RT \times i$
$7.8 = C \times 0.0821 \times 310 \times 2$
$C = 0.153 m o l e^{- 1}$
The concentration of on
aqueous Nacl solution that
is used in blood stream
is $0.15 m o l / L$
