Question

calculate molecular mass of CH4​

Answer 1

16

Explanation:

c =4 H =1 these are the molecular masses. so there are 4 hydrogen s it should be multiplied by4

Answer 2

Answer:

16.04 g/mol

Explanaiton:

Methane — CH4

Atomic mass of carbon- 12amu

Atomic mass of hydrogen- 1amu.

But due to the presence of 4 hydrogen atoms it's mass will be — 4×1= 4amu

So mass of methane : 12+4= 16amu
