How much sulphur is present in organic compound if on analysis $$0.53\ gm$$ of this compound gives $$1.158\ gm$$ of $$BaSO_{4}$$?

A$$10\%$$
B$$15\%$$
C$$20\%$$
D$$30\%$$
Correct Answer

Solution

Percentage of sulphur $$=\dfrac{32}{233}\times \dfrac{mass\ of\ BaSO_{4}}{mass\ of\ organic\ compound}\times 100$$

$$=\dfrac{32}{233}\times \dfrac{1.158}{0.53}\times 100=30\%$$
