The actual number of atoms of each element present in the molecule of the compound is represented by the formula known as molecular formula.
Molar mass of the unknown compound = 223.94 g/mol (given)
Mass of each element present in the unknown compound is determined as:
- Mass of carbon,
:
- Mass of hydrogen,
:
- Mass of chlorine,
:
Now, the number of each element in the unknown compound is determined by the formula:
- Number of moles of
- Number of moles of
- Number of moles of
Dividing each mole with the smallest number of mole, to determine the empirical formula:
Multiplying with 2 to convert the numbers in formula into a whole number:
So, the empirical formula is .
Empirical mass =
In order to determine the molecular formula:
n =
n =
So, the molecular formula is:
