The molar mass of the protein from the calculation is 1667 g/mol.
The osmotic pressure can be determined using the formula;
π=icRT
i = Van't Hoff factor = 1
c = concentration = ?
R = gas constant = 0.082 atmLK-1mol-1
T = temperature = 298 K
π= 2.24 torr or 0.029 atm
Now;
0.029 = 1 * c * 0.082 * 298
c = 0.029/1 * 0.082 * 298
c = 0.0012 M
Now;
2.00×10-3 g/MM = 0.0012 M * 1.00/1000L
MM = 2.00×10-3 g/0.0012 M * 1.00/1000L
MM = 1667 g/mol
