Which best describes the products of a chemical equation? 2 F2 + 11,0 = 1 OF, + 2HF A. Chemicals before the reaction starts B. Chemicals after the reaction ends C. Chemicals on the left of the arrow D. Chemicals on the right of the arrow​

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.

it is a solid

explanation:

you need to have a picture of the atom that way we can answer it
