In which of the following ways would you modify this sketch to show the analogous orbital for the n=4 shell: group of answer choices it would be drawn larger. another lobe would be added along the +x axis. the lobe on the +y axis would be larger than the lobe on the −y axis it doesn’t change.

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.
