Nutrient Value per Serving Value per Serving with 200 mL of Milk Iron 30% 30% Vitamin A 30% 40% Vitamin D 10% 25% Calcium 0% 30% Niacin 25% 25% Protein 4% 10% 4 Which of the nutrients in the above chart is in the milk but not the cereal? A. calcium B. niacin C. vitamin D D. iron

The answer is A. calcium

Explanation:

the value per serving in calcium is a 0% which makes milk the full 30%

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
