Answer:
CH
Explanation:
92.26% = 92.26 g
7.74% = 7.74 g
carbon is 92.26 x 1 mole/12.011 = 7.68
hydrogen is 7.74 x 1 mole/1.008 = 7.68
carbon 7.68 ÷ hydrogen 7.68 = 1
so 1 is your subscript for both carbon and hydrogen
The mass of atoms of carbon and 3 molecules of hydrogen : 18 g/mol
<h3>Further explanation
</h3>
An atomic mass unit ( amu or "u") is a relative atomic mass of 1/12 the mass of an atom of carbon-12.
The molar mass(molecular mass-formula mass-molecular weight(MW)) of a compound is the sum of the relative atomic mass (Ar) of the constituent elements of the compound
Can be formulated :
M AxBy = (x.Ar A + y. Ar B)
The mass of atom of Carbon(C)⇒Ar = 12 g/mol
The mass of 1 molecule of Hydrogen - H₂(MW) : 2 g/mol
The mass of 3 molecules of Hydrogen : 3 x 2 = 6 g/mol
So the mass of atoms of carbon and 3 molecules of hydrogen :

Answer:
I think that is the literal answer
