1.	the hemoglobin from the red blood corpuscles of most mammals contains approximately 0.33% of iron by mass. the molar mass of hemoglobin is 67 200 gm. the number of iron atoms in each molecule of hemoglobin is (atomic mass of iron = 56 amu):
Answer» 0.33 GM of iron in 100 gm of HEAMOGLOBIN molar mass of heamoglobin is 67,200 gm suppose x gm of iron is PRESENT in 67,200gm of Hb therefore, 0.33 - 100 x - 67200 0.33×67200/100 = 221.76 gm of iron now, mass of 1 ATOM of Fe =56 some atoms of mass of Fe= 221.76 let those some atoms be y therefore, 1 - 56 y - 221.76 1×221.76/56 = 3.96 atoms which is approximately by round off is 4.0 answer: 4 atoms of iron
