Please help this is one of my last questions. I really need this. Delete AC and focus on the
intersection of AB and BC.
Keeping points B and C fixed, move point A to different locations and observe how
ZABC changes. What must you do to increase or decrease m/ABC: What happens if you move point A to a location directly on CB? What is
ZABC at this location? Explain.

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 answer is true. hope it .
