Hello!
The answer is:
The empirical formula is the option B. [tex]NH_{3}[/tex]
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.
[tex]MolecularFormula=n(EmpiricalFormula)[/tex]
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. [tex]N_{2}O_{4}[/tex]
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.
[tex]N_{2}O_{4}=2(NO_{2})[/tex]
B. [tex]NH_{3}[/tex]
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. [tex]C_{3}H_{6}[/tex]
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.
[tex]C_{3}H_{6}=3(CH_{2})[/tex]
D. [tex]P_{4}O_{10}[/tex]
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.
[tex]P_{4}O_{10}=2(P_{2}O_{5})[/tex]
Hence, the empirical formula is the option B. [tex]NH_{3}[/tex]
Have a nice day!
The compound that represents empirical formula 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 empirical formula because it is the simplest whole number ratio of the compound.
