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

A

7.8 mol `L^(-1)`

B

1.5 mol `L^(-1)`

C

0.075 mol `L^(-1)`

D

0.15 mol `L^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
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)`

Osmotic pressure of a sugar solution at 24^(@)C is 2.5 atm. The concentration of the solution in gm mole per litre is :

The osmotic pressure of blood is 7.40 atm at 27^(@) C .The number of mol of glucose to be used per litre for an intravenous injection that is to have the same osmotic pressure as blood is

The osmotic pressure of blood is 8.21 atm at 310 K . How much glucose should be used per L for an intravenous injection that is isotopic with blood?

The osomotic pressure pi depends on the molar concentration of the solution (pi=CRT) . If two solutions are of equal solute concentration and, hence, have the same omotic pressure, they are said to be isotonic. If two solutions are of unequal osmotic pressures, the more concentrated solution is said to be hypertonic and the more diluted solution is described as hypotonic. Osmosis is the major mechanism for transporting water upward in the plants. Answer the following questions: The glucose solution to be injected into the bloodstream and the blood itself should have the same.
