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

Answer»

7.8 mol `L^(-1)`
1.5 mol `L^(-1)`
0.075 mol `L^(-1)`
0.15 mol `L^(-1)`

SOLUTION :NaCl SOL. used should be isotonic with blood STREAM.
For NaCl, `i=2, pi=iCRT`
or `C=(pi)/(iRT)=(7.8"bar")/(2xx0.083"bar LK"^(-1)"mol"^(-1)xx310K)`
`=0.15"mol L"^(-1)`
