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.

Options:

A .

3 : 1

B .

2 : 1

C .

1 : 3

D .

4 : 2

Answer: Option A
:
A

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 $= 12 : 4 = 3 : 1$
