There is a legend according to which a young man presented his beloved with a ring made of iron. Iron was obtained from the blood of a young man. a) Estimate how long it took the young man to excrete the required amount of iron from his blood. The boy's body weight is 80 kg. Blood makes up 8% of a person's weight, the density of blood is 1.050 g / ml, 100 g of blood contains 14 g of hemoglobin. The molar mass of hemoglobin is 68kg / mol (take into account the number of iron atoms in all subunits!). According to the rules for donating blood for men, it is safe to donate blood no more than 4-5 times a year (for calculations, use 4 times). During one collection, 450 ml is taken. b) To isolate iron from the blood, the blood was first centrifuged to separate hemoglobin, then the protein was destroyed with acid (that is, you have a solution containing iron cations). Suggest a further chain of reactions to obtain metallic iron. (write the reaction equations) take the mass of the ring 3 g
