How many moles of S are in 33.3 g of (C3H5) 2S

0.292 moles of S

Explanation:

The chemical formula (C₃H₅) ₂S may be of di (prop-1-en-1-yl) sulfane or it may be of diallylsulfane. First let us find the number of moles of each elemnet present in one mole of (C₃H₅) ₂S. i. e.

Element Moles

Carbon 6

Hydrogen 10

Sulfur 1

As one mole of (C₃H₅) ₂S weights 114 g so we can calculate the number of moles of S in 33.3 g of (C₃H₅) ₂S as,

114 g of (C₃H₅) ₂S contains = 1 mole of S

Then,

33.3 g of (C₃H₅) ₂S will contain = X moles of S

Solving for X,

X = (33.3 g * 1 mol) : 114 g

X = 0.292 moles of S
