The element found in the liver that helps prevent anemia is iron.
Iron is an essential element for blood production. Close to 70% of the body's iron is found in the red blood cells. In the red blood cells it is a vital ingredient of hemoglobin, the red pigment that gives blood its red color. In the muscle cells, iron is found as myoglobin.
Iron is stored mostly in the liver as ferritin or hemosiderin.
When iron stores are finished or exhausted, the condition is called iron depletion. When the shortage of iron is severe, it results in a condition known as iron deficiency anemia whereby the red blood cells do not have enough hemoglobin.
Answer:
Half life is the time taken by a radio active isotope to reduce by half of its original amount. Radium-226 has a half life of 1602 years meaning that it would take 1602 years for a mass of radium to reduce by half.
Number of half lives in 9612 years = 9612/1602 = 6 half lives
New mass = Original mass x (1/2)n where n is the number of half lives.
Therefore, New mass= 500 x (1/2)∧6
= 500 x 0.015625
= 7.8125 g
Hence the mass of radium after 9612 years will be 7.8125 grams.

Answer:
The mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.
