Answer 1

Answer

• ⇒ C₁₃H₂₆

Explanation

⇒ Given,

• Empirical formula of the compound = CH₂
• ∴ Empirical formula mass = 12 + 2 = 14 g/mole.
• Given,  molecular mass = 180 g.
• ∴ n = molecular mass/empirical formula mass

∴ n = 180/14

∴ n = 12.85 ≈ 13

∴ Molecular formula = n × empirical formula.

∴ Molecular formula = 13 × CH₂

∴ Molecular formula = C₁₃H₂₆

• Hence, the molecular formula of the given compound is C₁₃H₂₆.
