Question

The mass ratio of carbon to hydrogen in methane is 3:1. How much amount of hydrogen is required to react with 36 gms of carbon to form methane?

• A. 10 gm
• B. 12 gm
• C. 16 gm
• D. 30 gm

Answer 1

Answer: (B), (D)

The correct options are
B

12 gm

D

30 gm

The chemical formula of Methane is $C{H}_4$. The carbon to hydrogen weight ratio in it is 3:1.
It requires 3 grams of carbon for one gram of hydrogen. So, for 36 grams of carbon, we require 12 grams of hydrogen.
