What is the molar mass of CH4?
(C = 12.01 g/mol, H = 1.008 g/mol)

The molar mass of CH4 is 16.042 g

C= 12.01 g/mol

H= 1.008 g/mol

The calculation can be done as follows

= 12.01 ₊ 1.008(4)

=12.01 ₊ 4.032

= 16.042

Hence the molar mass is 16.042 g

The molar mass of CH4 (methane) is 16, 042 g/mol

Explanation:

We use the weight of the atoms C and H for calculate the molar mass:

Weight of CH4= weight C+ 4 x weight H= 12,01 g/mol +4 x 1,008g/mol=

Weight of CH4 =16, 042 g/mol
