Answer: The molecular formula will be
C_6O_3H_(12)

Step-by-step explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Empirical weight of
C_2OH_(4) is
12* 2+16* 1+1* 4=44g

Molecular mass of compound is = 132 g

Now we have to calculate the molecular formula.


n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=(132)/(44)=3

The molecular formula will be=
3* C_2OH_4=C_6O_3H_(12)
