Question

Problem quote "A sample of hemoglobin is found to be 0.335% iron.If hemoglobin contains one iron atom per molecule, what is themolar mass of hemoglobin? What is the molar mas if there are fourirons atoms per molecule?"

Now, I've been staring at this one for awhile writing seeminglyunhelpful equations down to see if anything clicks.

Molar mass = atomic weight X 1g/mole.
Fe = 55.845 amu

I'm honestly really lost. Could anyone start me off in the rightdirection? You don't need to give me the full answer if you don'twant, I know I'm new on here and need to start building somecredit. At least some tips, useful equations, or anything would befantastic and well appreciated.

Explanation / Answer

lets say we have 1 mol of hemoglobin we know there are 4 mol of iron atoms per mol hemoglobin so thatmakes 4x55.845g Fe we also know that the mass we just found is .335% of the mass divide the mass of the 4mol Fe by .00335 and you have your molarmass. repeat with just the 55.845g Fe/mol and youll have your molar masswith only 1 Fe per hemoglobin
