assuming you have 100 grams of sample
85.60gC/molecular weight 12g = 7.13
14.40gH/molecular weight 1.008g = 14.2857
divide the larger amount calculated by the smaller 14.2857/7.13 = 2
so 7.13 means oneC and 14.2857 means twoH
CH2 ethylene
[tex]CH_2[/tex] is the empirical formula of a substance that consists of 85.60% carbon and 14.40% hydrogen.
The empirical formula is defined as the formula of a compound which gives the simple whole-number ratio of the atoms of various elements present in one molecule of compound.
Assuming you have 100 grams of sample.
[tex]\frac{85.60g \;Carbon}{Molecular \;weight \;12g}[/tex] = 7.13g
[tex]\frac{14.40g \;Hydrogen}{Molecular \;weight \;1.008g }[/tex] = 14.2857
Dividing the larger amount by the smaller [tex]\frac{14.2857}{7.13}[/tex] = 2
So, 7.13 means one Carbon and 14.2857 means two Hydrogen atom.
Hence, [tex]CH_2[/tex] is the empirical formula of a substance that consists of 85.60% carbon and 14.40% hydrogen.
