Hint: The molecular formula is permanently a whole number multiple of the empirical formula.
The empirical formula is by classification the greenest whole-number ratio defining basic atoms in a type. The molecular formulas are always a whole number ratio of the empirical formula.
Molecular formula = (Empirical formula) $\times n$.
Complete step by step answer:
Molecular formula:
The molecular formula is the formula derivative from molecules and is demonstrative of the whole number of specific atoms present in a molecule of a compound.
A molecular formula follows a subscript that reports the actual number of each variety of atom in a molecule of the compound.
Molecular formulas are related with gram molecular masses that are modest whole number multiples of the consistent empirical formula mass.
Empirical formula:
The empirical formula is the greenest formula for a compound which is well-defined as the ratio of subscripts of the smallest likely whole number of the elements existing in the formula. It is also well-known as the simplest formula.
An empirical formula for a compound is the formula of a substance written with the minimum integer subscript.
The empirical formula gives information nearby the ratio of numbers of atoms in the compound. The percent conformation of a compound directly leads to its empirical formula.
Relation between empirical and molecular formula:
Let’s take the sample of Glucose. The molecular formula of Glucose is \[{C_6}{H_{12}}{O_6}\] and the empirical formula of Glucose is \[C{H_2}O\]. We can develop a relative between the Molecular formula and the empirical formula of Glucose.
Empirical Formula and Molecular Formula of Butane and Octane
\[{C_6}{H_{12}}{O_{6\;}} = {\text{ }}6{\text{ }} \times \;C{H_2}O\]
We can derive a common communication as,
Molecular formula = n X empirical formula
where n is a whole number
Sometimes, the empirical formula and molecular formula mutually can be similar.
Note:
The empirical formula of a compound gives the greenest ratio of the number of dissimilar atoms existing, whereas the molecular formula gives the real number of each changed atom present in a molecule. If the formula is basic then it is an empirical formula.
