Bob and Ada are camping and have sweet potatoes wrapped in foil to eat. Ada put her sweet potato in the bonfire for a while, but Bob did not. Now Ada’s sweet potato has a high temperature. What is the difference between the molecules of the two potatoes?

one of the sweet potatoes atoms are moving really fast and the other sweet potatoes atoms isn't  moving.

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.
