Explanation:
the empirical formula is correct but I didn't got the question properly
The empirical formula for a compound that contains 48.6%C, 8.2% H, and 43.2% S by mass is
.
<h3>What is the empirical formula?</h3>
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
