Hemoglobin is the protein that transports oxygen in mammals. Different species of mammals have slightly different forms of hemoglobin. One form of hemoglobin is 0.346% fe by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of this form of hemoglobin.

Answer;

= 64561.95 g/mole

Explanation;

mass of Fe in 100g =.346g

=.346 / 55.8452 moles

= 0.0061957 moles

These represent 4 moles of Fe in the molecule so moles of hemaglobin

= 0.0061957/4

= 0.0015489 moles

these are in 100 g so mass of 1 mole = 100 / 0.0015489

= 64561.95 g / mole

molar mass of hemoglobin = 64561.95 g/mole
