Hemoglobin is the oxygen carrying compound found in human blood. It is found to contain 0.3335% iron by mass. It is already known that one molecule of hemoglobin contains four atoms of iron. What is the molecular mass of hemoglobin in g/mol

Answer:

66986.51 g/mol

Explanation:

According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.

* One molecule of hemoglobin contains four atoms of iron

If 1 atom of Fe = 55.85g/mol

Then 4 atoms = 4 × 55.85 = 223.4g/mol

So there are 223.4g/mol of Fe in one molecule of hemoglobin

If hemoglobin contains 0.3335% iron by mass, this mathematically means that:

223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%

That is;

223.4/M.M = 0.3335/100

Cross multiply

0.3335 M.M = 22340

M.M = 22340 ÷ 0.3335

M.M = 66986.51

Hence, the molar mass of hemoglobin is 66986.51g/mol.
