Assume human blood is iso-osmotic or isotonic with a 0.16 mol/lit saline (NaCl) solution (the solution does not change the volum

e of the blood cell) and for simplicity all dissolved salts in the solution are NaCl rather than ions. Estimate osmotic pressure at 37°C.

Answer:

π = 4.1 atm

Explanation:

We can calculate the osmotic pressure exerted by a solution using the following expression.

π = M . R . T

where,

π is the osmotic pressure

M is the molar concentration of the solution

R is the ideal gas constant

T is the absolute temperature

The absolute temperature is 37 + 273 = 310 K

π = M . R . T

π = (0.16 mol/L) . (0.082atm.L/mol.K) . 310 K = 4.1 atm
