A sample of heme a constituent of haemoglobin , weighs 35.2 mg and contains 3.19 mg of iron ,than its molecular mass is ???

Dear Student,

The computation are expressed below,

Mass of Fe = 3.19 mg = 0.00319 gMolar mass of Fe = 55.8 gmolNo.of. moles of Fe = 0.0031955.8=0.0000572 molesMass of Hb=35.2 mg = 0.0352 gMolar mass of Hb = 0.03520.000057=617.9 gmol

Regards.
