Answer 2

Given: Given compounds are methane and carbon monoxide.

To find: We have to find the molecular mass.

Solution:

The chemical formula of methane is $CH_4$.

The atomic mass of C is 12 and H is 1.

Methane has one C and four hydrogen atoms.

So, the molecular mass of methane is as follows-

12+4×1=16.

The molecular mass of methane is 16g.

The chemical formula of carbon monoxide is $CO$.

The atomic mass of C is 12 and O is 16.

Carbon monoxide has one C and one oxygen atom.

So, the molecular mass of carbon monoxide is as follows-

12+16=28

The molecular mass of carbon monoxide is 28g.
