[tex]N_{2} O_{4}[/tex] is the molecular formula.
How do we calculate the Molecular formula?
- Subtract the empirical formula molar mass from the molar mass of the compound.
- The result must be exactly one or very close to it.
- The whole number discovered in step 2 is multiplied by each subscript in the empirical formula.
- The end result is the molecular formula.
- The simplest whole-number ratio of the different atoms in a compound is an empirical formula.
- The number of various atom types that make up a compound molecule is specified by the molecular formula.
- We can obtain the whole-number multiple for the compound using the supplied molar mass or the mass of the molecular formula.
Multiplying the subscripts [tex]N O_{2}[/tex] by 2, the molecular formula is
2[tex]N O_{2}[/tex] = [tex]N_{2} O_{4}[/tex]
[tex]N_{2} O_{4}[/tex] is the molecular formula.
