Electronegativity increases when atoms . A. are located on the right on the periodic table
B. have a large atomic radius
C. have a small atomic radius
D. are located on the left on the periodic table

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 product of the pressure and volume is also constant

58750.08068 is the answer i think

gold is my favorite solid.
