One molecule of haemoglobin will combine with four molecules of oxygen. If

1.0 \mathrm{~g}

of haemoglobin combines with

1.642 \mathrm{~ml}

of oxygen at body temperature

\left(27^{\circ} \mathrm{C}\right)

and a pressure of 760 torr, then what is the molar mass of haemoglobin?

View answer and explanation

Correct option: D

60,000

Option D (60,000) is correct because the molar mass of hemoglobin is calculated using the ideal gas law and the stoichiometry of oxygen binding to hemoglobin.
