The empirical formula for the given compound is

Explanation:

Let us assume that the mass of the compound be 100 grams.

So, the percentage of the elements will be equal to their respective masses.

Mass of aluminium = 35.94 g

Mass of sulfur = 64.06 g

To find the empirical formula for a compound, we follow some steps:

Step 1: Converting the given masses of the elements into moles.

To calculate moles, we use the equation:

Moles of aluminium =

Moles of sulfur =

Step 2: Now, dividing each calculated moles by the smallest number of moles, which is 1.33 moles, to calculate the mole ratio of elements.

Mole ratio of aluminium =

Mole ratio of sulfur =

Step 3: Converting the mole ratio into whole number ratio.

Multiplying both the ratios by 2, to make both the mole ratios to be a whole number.

Mole ratio of aluminium =

Mole ratio of sulfur =

Step 4: Writing each mole ratio as the subscripts of the elements to make the empirical formula.
