The empirical formula of an organic compound is C2H4O. The molecular mass of the compound is 176g/mol.

What is the molecular formula of this compound?

Respuesta :

Answer:

The molecular formula of the compound is [tex]C_{8}H_{16}O_{4}[/tex].

Explanation:

Given empirical formula of the compound is [tex]C_{2}H_{4}O[/tex].

Atomic mass of carbon = 12 u

Atomic mass of hydrogen = 1 u

Atomic mass of oxygen = 16 u

Empirical formula mass of compound = [tex]\left ( 12\times 2+4+16 \right ) = 44 \textrm{ g/mol}[/tex]

Molecular mass of compound = 176 g/mol

[tex]n = \displaystyle \frac{176}{44} = 4[/tex]

Molecular formula = n [tex]\times[/tex] Empirical formula

Molecular formula = 4 [tex]\times[/tex] [tex]C_{2}H_{4}O[/tex]

Molecular formula of the compound is [tex]C_{8}H_{16}O_{4}[/tex]
