The human body contains on average 5 liters of blood, the density of which is 1.050 g / ml. How many grams of iron is in human blood if the mass fraction of hemoglobin is 12%, and the mass fraction of iron in it is 0.5%?
the mass of blood in the body is 5000 * 1.050 = 5250g
hemoglobin mass = 5250 * 0.12 = 630 g
iron mass in hemoglobin = 630 * 0.5 = 315 grams
answer 315 grams
