Question

Calculate the molar mass of CH₄.

Answer 1

1. Molar mass is the sum of the masses of all the individual atoms present in a molecule or compound.
2. The chemical formula of Methane is CH₄
3. Methane CH₄ is a hydrocarbon which belongs to the category of alkane.
4. The atomic mass of carbon C is 12 u.
5. The atomic mass of hydrogen H is 1u
6. $\mathrm{Molar}\mathrm{mass}\mathrm{of}{\mathrm{CH}}_4=(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{carbon})\mathrm{x}1+(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{hydrogen})\mathrm{x}4$

$=(12\mathrm{x}1)+(1\mathrm{x}4)$

$=16\mathrm{g}$

The molar mass of CH₄ is 16g.
