Answer: The molecular formula of compound is [tex]C_6H_6O_6[/tex]
Explanation:
We are given:
Empirical formula of compound = CHO
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]
We are given:
Mass of molecular formula = 180 g/mol
Mass of empirical formula = 29 g/mol
Putting values in above equation, we get:
[tex]n=\frac{180g/mol}{29g/mol}=6.20\approx 6[/tex]
Multiplying this valency by the subscript of every element of empirical formula, we get:
[tex]C_{(1\times 6)}H_{(1\times 6)}O_{(1\times 6)}=C_6H_6O_6[/tex]
Hence, the molecular formula of compound is [tex]C_6H_6O_6[/tex]
