Answer:
C₄H₈
Explanation:
Molecular Formula: The molecular formula of a compound gives the exact number of moles of atom of the component elements in one mole of the compound.
From the question,
Molecular formula = (CH₂)ₙ
(CH₂)ₙ = 56................ Equation 1
Where the molar mass of C = 12 g/mole, H = 1 g/mole.
Substitute into equation 1
[12+(1×2)]ₙ = 56
(12+2)ₙ = 56
14n = 56
n = 56/14
n = 4
Molecular formula = (CH₂)₄
molecular formula = C₄H₈
Hence the molecular formula of the compound is C₄H₈
