Torn paper vs burned paper? Coloring leaves in a coloring book vs leaves turning colors during fall and winter?
Describe the physical and chemical changes of each

physical- torn paper, coloring leaves in a coloring book

chemical- burned paper, leaves turning colors during fall and winter

Explanation:

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.

the maximum mass of nh3 is nh3 in grams
