Answer:
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
Osmotic pressure of human blood at 25 degree C or at absolute temperature is equal to 7.33 atm.
What is osmotic pressure?
It is defined as the minimum pressure exerted on the solution, which is required to stop the flow of pure solvent from low concentration to high concentration through the semi permeable membrane.
Osmotic pressure can be calculted as :
P = M × R × T
Where, P = Osmotic pressure
M = Molar mass = 0.30 M (given)
R = Universal gas constant = 0.082 atmL/molK
T = Absolute temperature 25 degree C = 25⁰C + 273.15 = 298.15 K
Putting all these values in the given equation, we get:
P = 0.30 × 0.082 × 298.15 = 7.33 atm
Hence, 7.33 atm is the osmotic pressure of blood at 25⁰C .
