Determine the empirical formula of an oxide of sulphur containing 60% of oxygen

[S = 32, O = 16 ]

Oxide of Sulphur means the compound formed is bonding between Sulphur and Oxygen.

Also, if the compound contains 60% Oxygen, then it must contain 40% Sulphur

Elements S O

%by mass of atoms 40 60

Divide by their masses \(\frac{40}{32}\) \(\frac{60}{16}\)

1.25 3.75

Divide through by smaller value \(\frac{1.25}{1.25}\) \(\frac{3.75}{1.25}\)

1 : 3

Empirical formula SO\(_3\)
