For this problem, we are being asked to calculate the # of Fe2+ ions in one molecule of hemoglobin
Step 1. Find the mass of 1 molecule of hemoglobin
Step 2. Find the mass of Fe2+
Hemoglobin, a protein in red blood cells, carries O 2 from the lungs to the body’s cells. Iron (as ferrous ion, Fe2+) makes up 0.33 mass % of hemoglobin. If the molar mass of hemoglobin is 6.8×104 g/mol, how many Fe2+ ions are in one molecule?
