We take as a basis for solving this item, 100 g of sample. If 15.77%
of the sample is carbon, we solve for the amount of carbon in the sample,
Carbon = (100
g)(0.1577) = 15.77
Then, we solve for the amount sulphur in the sample by,
Sulfur = (100 g)(1 – 0.1577)
= 84.23 g
Next, we solve for the number of moles of the elements by dividing the
calculated masses by the molar mass.
Carbon = (15.77g)(1 mol/12 g) =
1.3 moles
Sulphur = (84.23 g)(1 mol/32 g)
= 2.63 moles
From the ratio of the calculated number of moles, we can say that each
mol of carbon will have to be paired up with two other sulphur atoms. Thus, the
shape of the molecule is <em>LINEAR. </em>
