question 3 options:

move at a constant rate to the left

move at a constant rate to the right

accelerate to the left

accelerate to the right

it is 1 2 4 i took the test i got 100 percent A Hope it helps ;)

your answers are a,b,,e and f

i hope this

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.
