Which of the following compounds have the same empirical formula? CO2 and SO2
C7H14 and C10H20
C4H10 and C10H4
CoH12 and CoH14

C₇H₁₄ and C₁₀H₂₀

Explanation:

The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio of the atoms of the different elements that makes up the compound.

 C₇H₁₄ and C₁₀H₂₀

 In both species if we divide the number of atoms by the simplest common factor, we get CH₂

   C₇H₁₄  = CH₂ dividing by 7

   C₁₀H₂₀ =  CH₂ dividing by 10
