Human blood has a molar concentration of solutes of 0.30 M. What is the osmotic pressure of blood at 25°C?

π = 7.33atm

Explanation:

Osmotic pressure is defined as the pressure that must be applied to stop the mass transfer when a semipermeable membrane separates it of pure water. The equation is:

π = M×R×T

Where P is osmotic pressure

M is molar mass = 0.30M

R is gas constant = 0.082atmL/molK

And T is absolute temperature = 25°C + 273.15 = 298.15K

π = 0.30M×0.082atmL/molK×298.15K
