Hemoglobin is a protein molecule which contains 4 iron atoms.If the mass percent of iron is 0.342%,what is the molar mass of hemoglobin?

Question

Quizplus · Accepted Answer

Let the molar mass of hemoglobin be M. From the given information,
mass of iron in 1 mole of hemoglobin = M × 0.00342
mass of iron in 4 atoms of iron = 4 × atomic mass of iron
Equating both the masses and solving, we get M = 65,300 g/mol. Therefore, the correct option is C.
