Calculation of Osmotic Pressure of Protein Polymer Solution


Given Data:


  • Mass of Polymer: 1 g

  • Molar Mass of Polymer: 16×10^4 g/mol

  • Volume of Solution: 800 mL = 0.8 L

  • Temperature: 300 K



Formula Used:

Osmotic Pressure (π) = (n/V)RT

Where,

  • n: Number of moles of solute

  • V: Volume of solution

  • R: Universal gas constant = 8.314 J/mol-K

  • T: Temperature in Kelvin



Solution:


  • Number of moles of solute:
    n = Mass of solute/Molar mass of solute
    = 1 g/16×10^4 g/mol
    = 6.25×10^-5 mol

  • Osmotic Pressure:
    π = (n/V)RT
    = (6.25×10^-5 mol/0.8 L)×8.314 J/mol-K×300 K
    = 1.55×10^3 Pa (Pascal)



Conclusion:

The osmotic pressure of the protein polymer solution at 300 K is 1.55×10^3 Pa. Osmotic pressure is a colligative property of a solution that depends on the number of solute particles in the solution but not on their size or nature. It is an important parameter in many biological and chemical processes, including osmosis, dialysis, and reverse osmosis.
