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.

Thus the compound with molecular formula will have simplest ratio of atoms as 3:6:1:1 and thus empirical formula will be .

the answer
