Answer:
C₅H₁₀SO₂
Step-by-step explanation:
From the given information:
The objective is to identify the empirical formula of the compound.
To start with determining the mass of carbon from carbon dioxide; we have:

Mass of carbon = 12/44 × 57.271 mg
Mass of carbon = 0.2727 × 57.271 mg
Mass of carbon = 15.6178 mg
The mass of hydrogen is:


Mass of hydrogen = 2.6257 mg
The mass of sulphur is:

Mass of Sulphur =

Mass of Sulphur = 6.9550 mg
The Mass of oxygen can now be = mass of (Sample - Carbon - Hydrogen - Sulphur)
= (32.149 - 15.6178 - 2.6257 - 6.9550)g
= 6.9505 g
Recall that:
number of moles = mass/molar mass
Thus:
The moles of C : H : S : O are:

= 1 : 2 : 0.2 : 0.4
Divide by the smallest; we have:
= 1/0.2 : 2/0.2 : 0.2/0.2 : 0.4/0.2
= 5 : 10 : 1 : 2
Thus, the empirical formula is = C₅H₁₀SO₂
