Question

Calculate the molecular masses of the following compounds  :

Methane, CH₄

(Atomic masses : C = 12 u ; H = 1 u)

Answer 1

Given:

Atomic mass of C = 12 u

Atomic mass of H = 1 u

Therefore, molecular mass of CH₄ (methane) can be calculated as follows:

(1 × 12) + (4 × 1) = 16

Hence, molecular mass of methane is 16 u.
