c. a gallon of milk
d. a jar of mixed nuts

D. a jar of mixed nuts you can see them difference with mixed nuts but with the other options they are the same so you cant tell it apart

hope this helps:)sorry if it doesnt

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.
