Which molecular formula is also an empirical formula?

A. PCl3

B. C2H4

C. H2O2

D. C6H12O6

The molecular formula  is also an empirical formula.

Explanation:

Empirical formula of a compound represents the simplest positive integer ratio of constituting atoms.

Molecular formula may or may not be equal to empirical formula.

In general, if is the empirical formula then molecular formula is where n = 1, 2, 3......

                   Empirical formula                            Molecular formula

                                                                         or      

                           OH                                                 or

                                                                      or

Hence the molecular formula  is also an empirical formula.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
