Question

find the mass percentage composition of methane​

Answer 1

Answer:

In methane there are only 2 elements, Carbon and Hydrogen.

The total mass of a methane molecule (CH4) is

4 x 1 + 12 = 16.

%mass of H in methane= 4/16 x 100% = 25%

%mass of C in methane = 12/16 x 100% = 75%

Answer 2

Answer:

Here is your answer.....

In methane there are only 2 elements, Carbon and Hydrogen.

The total mass of a methane molecule (CH4) is

4 x 1 + 12 = 16.

%mass of H in methane= 4/16 x 100% = 25%

%mass of C in methane = 12/16 x 100% =75%
