The molecular formula of compound will be [tex]C_{3} H_{6} O_{3}[/tex].
an expression indicating the quantity and kind of atoms in such a substance's molecule, is referred as molecular formula.
A chemical compound would seem to be a substance made up of numerous similar molecules made up of atoms from different elements and kept together through chemical bonds. Consequently, a molecule made up of only one type of atom cannot even be a compound.
Calculation of molecular formula:
Molecular formula can be determined by using the formula:
Let [tex](CH_{2} O)n[/tex] be molecular formula,
(12+1+1+16)n=90.08
30n=90.08
n=3
The relation between molecular formula and empirical formula can be expressed as :
[tex]Molecular formula = (empirical formula)_{n}\\Molecular formula = (CH_{2} O)_{3} \\Molecular formula = C_{3} H_{6} O_{3}[/tex]
Therefore, the molecular formula will be [tex]C_{3} H_{6} O_{3}[/tex].
