Respuesta :

The molecular formula of the compound which has a molecular weight of 112.124 atomic mass units is C₆H₈O₂.

What is molecular formula?

Molecular formula of any compound tells about the composition and numbers of each entities present in that molecule.

Steps involved in the prediction of molecular formula:

  • First we predict the molar mass of given emperical formula as:

      Molar mass of C₃H₄O = 3(12) + 4(1) + 16 = 56

  • Now we divide the given mass by the calculated mass of empirical formula:

        112.124/56 = 2

  • Now we multiply the subscripts of given empirical formula by this whole number and we get:

        Molecular formula = (C₃H₄O)₂ = C₆H₈O₂

Hence correct option is (E).
