Respuesta :

The Al to Cl ratio is [tex]\frac{0.0200}{0.060} = \frac{1}{3}[/tex]. Meaning that there is 1 Al to every 3 Cl, and so the empirical formula is [tex]AlCl_{3}[/tex].

Answer:

Empirical formula for the given elements = [tex]AlCl_3[/tex]

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 = [tex]\frac{0.0200 mol}{0.0200 mol} =1[/tex]

Calcium = [tex]\frac{0.600 mol}{0.0200 mol} =3[/tex]

Empirical formula for the given elements = [tex]AlCl_3[/tex]
