Which statement best explains the process occurring in step 2 of the diagram?
A. Fertilized eggs are laid on water plants or released into water.
B. Egg cells are fertilized inside the female's body.
C. A zygote develops into an embryo inside each fertilized egg.
D. A nymph emerges from a fertilized egg and changes into an adult.

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.
