Answer : The molecular formula of the compound will be, [tex]C_{12}H_{24}O_{12}[/tex]
Explanation :
Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound. Â
Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound. Â
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
[tex]n=\frac{\text{molecular mass}}{\text{empirical mass}}[/tex]
As we are given that the empirical formula of a compound is [tex]CH_2O[/tex] and the molar mass of compound is, 360 gram/mol.
The empirical mass of [tex]CH_2O[/tex] = 1(12) + 2(1) + 16 = 30 g/eq
[tex]n=\frac{\text{molecular mass}}{\text{empirical mass}}[/tex]
[tex]n=\frac{360}{30}=12[/tex]
Molecular formula = [tex](CH_2O)_n=(CH_2O)_12=C_{12}H_{24}O_{12}[/tex]
Thus, the molecular formula of the compound will be, [tex]C_{12}H_{24}O_{12}[/tex]
