Question

In a biogas plant, methane gas ($C{H}_4$) is produced as a fuel. Find the mass ratio of carbon to hydrogen in methane.

• A. $3:1$
• B. $2:1$
• C. $1:3$
• D. $4:2$

Answer 1

The correct option is A

$3:1$

Mass of one carbon atom = 12u
Mass of each hydrogen atom = 1u
Mass of 4 hydrogen atoms = 4u
Mass ratio of carbon and hydrogen atoms in methane $=12:4=3:1$
