The empirical formula for a compound that contains 48.6%C, 8.2% H, and 43.2% S by mass is .
An empirical formula tells us the relative ratios of different atoms in a compound.
We need to calculate the number of moles
Number of a mole of carbon =
48.6 g X () =4.05 mole
Number of a mole of hydrogen =
8.2g X () =8.14 mole
Number of moles of sulphur =
43.2g X () = 1.35 mole
Dividing each mole using the smallest number that is divided by 1.35 moles.
Carbon= =3
Oxygen= =6
Sulfur= =1
