Vitamin B12 is a water-soluble vitamin that cannot be absorbed by the intestinal mucosa unless it has been bound to intrinsic factor.
Intrinsic factor is a glycoprotein secreted by the stomach that is essential for the absorption of vitamin B12. Vitamin B12 is essential for the synthesis of DNA and for the maintenance of normal red blood cells.
Vitamin B12 is an important nutrient that helps keep the body's nerve and blood cells healthy. It also helps make DNA, the genetic material in all cells. Vitamin B12 is found in animal foods such as meat, poultry, fish, and dairy products.
The body needs vitamin B12 to make red blood cells, which carry oxygen throughout the body. Vitamin B12 is also needed for proper brain function and to prevent a type of anemia called megaloblastic anemia, which makes people tired and weak.

Answer:
500 mg Ampicillin
Explanation:
given data
molecular weight = 349 g/mole
need = 10 ml of a 1000 x solution
solution
we get here for 50 μg / mL
here 10 ml of a 1000 x solution
so here need to weight is =50 μg × 10 = 500μg
so we were to prepare 1000 x
so here we get weight that is
we should weight = 500μg × 1000
so it is = 500 mg / 10 mL
