Answer:

Molecular formula = C₁₀H₂₀

Explanation:

Given data:

Empirical formula = CH₂

Molar mass = 140.27 g/mol

Molecular formula = ?

Solution:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Now we will calculate the empirical formula mass.

CH₂ = 12 × 1 + 1× 2

CH₂ = 12 +2

CH₂ = 14  

n = 140.27 / 14

n = 1 0

Molecular formula = n (empirical formula)

Molecular formula = 10 (CH₂)

Molecular formula = C₁₀H₂₀
