Answer:
Molar Mass of hemoglobin is [tex]67992[/tex]g/mol
Explanation:
As we know that
[tex]PV = nRT[/tex]
Where "P" signifies pressure, "V" signifies volume, "R" signifies gas constant, "T" signifies temperature and "n" signifies number of moles.
[tex]P = 743 / 760 = 0.978[/tex] atm
[tex]T = 37 + 273 = 310[/tex] K
Substituting the given values in above equation, we get -
[tex]n = \frac{0.978 * 1.99 * 10^{-3}}{0.08206 * 310} \\n = 7.65 * 10^{-5}[/tex] moles of oxygen
Number of moles of hemoglobin is [tex]\frac{1}{4}[/tex] of moles of oxygen
[tex]= \frac{1}{4} * 7.65 * 10^{-5}\\= 1.912 * 10^{-5}\\[/tex] moles
Molar mass of hemoglobin is equal to weight of hemoglobin divided by number of moles of hemoglobin
[tex]= \frac{1.30}{1.9125 * 10^{-5}} \\= 67992[/tex] g/mol
