Respuesta :

Empirical formula mass

  • 12+2
  • 14g/mol

Find n

  • Molecular mass/Empirical mass
  • 98.1861/14
  • 7

Molecular formula

  • n×Empirical formula
  • 7(CH2)
  • C_7H_14

The molecular formula of the compound is C₇H₁₄.

What is the relationship between empirical formula and molecular formula?

The empirical formula of a compound and the molecular formula is related as follows:

  • Molecular formula = n x empirical formula

The empirical mass of the compound = 12 + 4 = 14

n = molecular mass/empirical mass

n = 98.1861/14 = 7

molecular formula will be n(CH2) = C₇H₁₄

In conclusion, the molecular formula is determined from the molecular mass and empirical mass.
