प्रश्न
Calculate the molecular masses of the following compounds :
Methane, CH4
(Atomic masses : C = 12 u ; H = 1 u)
उत्तर
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.
