Answer:- Molecular formula of the sugar is [tex]C_6H_1_2O_6[/tex] .
Solution:- An empirical formula of the sugar is [tex]CH_2O[/tex] and it's molecular ion peak is 179.9. It means the molecular mass of the sugar is 179.9 gram per mol.
Empirical formula mass of the sugar = 12 + 2(1) + 16 = 30
Number of empirical formula units = [tex]\frac{179.9}{30}[/tex] = 6
From above calculations it is clear that six empirical formula units makes the molecular formula of the sugar.
So, the molecular formula of the sugar is [tex]C_6H_1_2O_6[/tex] .
