Question

A compound which contains only carbon, hydrogen, and sulfur is burned in oxygen under such conditions that the individual volumes of the reactants and products can be measured at the same temperature and pressure. it is found that 3 volumes of the compound react with oxygen to yield 3 volumes of carbon dioxide, 3 volumes of sulfur dioxide, and 6 volumes of water vapor. What is the formula of the compound? Is this an empirical or a molecular formula?

Answer 1

3CxHySz + 9O2 ==> 3CO2 + 3SO2 + 6H2O OR
1CxySz + 9/2 O2 ==> 1 CO2 + 1SO2 + 2H2O
CH2S emirical formula.

Answer 2

Assuming all of the carbon, hydrogen, oxygen and sulfur come from the reactants given and n-volumes means 'molar' volumes, then ...
CₓHᵥSₑ + 9O₂ => 3CO₂ + 6H₂O + 3SO₂
=> C₃H₁₂S₃ + 9O₂ => 3CO₂ + 6H₂O + 3SO₂
=> Empirical Formula => CH₄S

Answer 3

Oops! miss read question... '3'Vm of compound reacts... Dr Bob's solution is correct.
