Question

A 0.34g sample of compound of iron sulfide was found by analysis to contain

0.204g of iron and 0.136g of sulphur. Calculate the percentage composition of the

compound by weight.​

Answer 1

Answer⤵️⤵️

When a mixture of iron and sulphur is heated strongly, they first absorb the energy to get excited. This is followed by the formation of a new compound iron sulphide (FeS) with the release of huge amount of energy in the form of heat.... Therefore, heat is liberated out in the reaction...

Answer 2

Answer:

iron = 60%

sulphur = 40%

Explanation:

Percentage of iron = 0.204/0.34*100 = 60%

percentage of sulphur = 100 - percentage of iron = 40%
