Question

4 g carbon were heated with 8 g of sulphur. How much carbon disulphide (CS2) will be formed when the reaction is completed? What will be its percentage purity?  

Solution

Correct option is

79.2%

 

C      +     2 S    →     CS2

12g          2 × 32         12 + 2 ×3 2

               = 64 g        = 76 g

Obviously, sulphur will be the limiting reactant.

8 g sulphur will produce 

Carbon reacted 

Total mass of products
