List the number of each atom in the formulas above: h o c i just need the carbon

In all all the given formulas the number of  atoms of hydrogen , oxygen and carbon are same that 8,1 and 3 respectively.

Explanation:

Point at which lines are intersecting is denoted as carbon atoms

Number of atoms of different elements in following formulas:

1)

Number of hydrogen atom = 8

Number of carbon atoms = 3

Number of oxygen atoms = 1

2)

Number of hydrogen atom = 8

Number of carbon atoms = 3

Number of oxygen atoms = 1

3)

Number of hydrogen atom = 8

Number of carbon atoms = 3

Number of oxygen atoms = 1

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.
