Question

at 37 degrees Celsius, 0.30M sucrose has about the same osmotic pressure as blood. What is the osmotic pressure of blood?

Answer 1

We know the osmotic pressure of a nonvolatile nonelectrolyte solution is

$\Pi$ =CRT

C=molar concentration of electrolyte=0.30(M),

R=universal gas constant=0.082L-atm/mol k

T=kelvin temperature=37+273=310K

Putting all these value in above equation we get$\Pi$ =(0.30*0.082*310)atm=7.62atm,as the blood has same osmotic pressure with sucrose solution the osmotic pressure of blood is 7.62atm
