  • The atomic mass of carbon is 12.011 g/mol.
  • The atomic mass of hydrogen is 1.00794 g/mol.
  • The atomic mass of sulfur is 32.06 g/mol.

This means that the molar mass of [tex]\text{C}_{2}\text{H}_{4}\text{S}[/tex] is

[tex]2(12.011)+4(1.00794)+32.06=60.11376[/tex]

Dividing this by the given molar mass, we get [tex]\frac{168}{60.11376} \approx 3[/tex]

So, the molecular formula is about [tex]\boxed{\text{C}_{6}\text{H}_{12}\text{S}_{3}}[/tex]
