The Empirical Formula Of A Compound Is CH2 The Molecular Mass Is 70 G/mol What Is The Molecular Formula?

Molecular formula = n( empirical formula)

Empirical formula = CH2

n= molecular formula mass/ empirical formula mass

Molecular mass = 70 grams per mole

Empirical formula mass = mass of carbon + 2* mass of hydrogen

Empirical formula mass = 12 + 2*1

Empirical formula mass = 14 grams per mole

n= 70/ 14

n= 5

Molecular formula = n( empirical formula)

Molecular formula = 5(CH₂)

Molecular formula = C₅H₁₀
