The compound that represents empiricalformula is NH3.
EMPIRICAL FORMULA:
- Empirical formula refers to formula of a compound that depicts the simplest whole number ratio of its constituent element.
- The empirical ratio of the elements of a compound should not be able to be broken down further. For example: compounds such as N2O4, C3H6, and P4O10 can be further broken down into NO2, CH2 and P2O5.
- This means that NH3 is the empiricalformula because it is the simplest whole number ratio of the compound.

Hello!
The answer is:
The empirical formula is the option B.
Why?
The empirical formula of a compound is the simplest formula that can be written. On the opposite, the molecular formula involves a variant of the same compound, but it can be also simplified to an empirical formula.
We are looking for a formula that cannot be simplified by dividing the number of molecules/atoms that conforms the compound.
Let's discard option by option in order to find which formula is an empirical formula (cannot be simplified)
A.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
B.
It's an empirical formula since it cannot be obtained by the multiplication of a whole number and the simplest formula. It's the simplest formula that we can find of the compound.
C.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
D.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
Hence, the empirical formula is the optionB.
