mols Fe = grams Fe/atomic mass Fe.
mols hemoglobin = 1/4 that since there are 4 atoms/molecule
mols hemoglobin = grams/molar mass. You know grams ad mols, solve for molar mass. I get something like 65,000 give or take a little.
Hemoglobin is the oxygen carrying molecule of red bloods and contains 4 atoms of iron per molecule of hemoglobin. A sample of hemoglobin weighing 13.4 g contains 45.6 mg iron. What is the molecular mass of hemoglobin?
I'm unsure of where to begin with this problem. I know g/mol = amu so I've been trying to get the molar mass to know the molecular mass.
Please explain, thanks!
