10. Write the molecular formula for the
compound with the following skeletal
structure.
(Hint: Draw a full structural formula, and
include all the carbon and hydrogen atoms
in your count.)
HN
is
As?

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.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

i'm wiling to try and you : )

the answer is c.the valence of the atoms combine .
