To calculate the molecular mass of haemoglobin, we need to take into account the molar mass of iron (Fe) and the molar mass of the other elements in haemoglobin (carbon, hydrogen, nitrogen, and oxygen).
Given that the haemoglobin molecule contains 0.33% iron by mass, this means that the remaining 99.67% of the mass is due to the other elements. Since there are 2 Fe atoms in 1 molecule of haemoglobin, the total mass of iron in 1 molecule is:
0.33% * molecular mass = 2 * molar mass(Fe)
(0.33/100) * x = 2 * 55.845
x = (2 * 55.845) / (0.33/100)
x = 33682.57
Therefore, the molar mass of haemoglobin is approximately 33682.57 u.
