Answer:
Empirical formula for the given elements = \(AlCl_3\)
Explanation:
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Moles of aluminum = 0.0200 mol
Moles of chlorine = 0.0600 mol
For empirical formula , divide the smallest number of moles from each moles of element.
Aluminium = \(\frac{0.0200 mol}{0.0200 mol} =1\)
Calcium = \(\frac{0.600 mol}{0.0200 mol} =3\)
Empirical formula for the given elements = \(AlCl_3\)
