प्रश्न
Calculate the molecular masses of the following :
Carbon dioxide, CO2
(Atomic masses : H = 1 u ; O = 16 u ; Cl = 35.5 u ; N = 14 u ; C = 12 u)

उत्तर
Given:
Atomic mass of C = 12 u
Atomic mass of O = 16 u
Therefore, molecular mass of CO2 can be calculated as follows:
(1 × 12) + (2 ×16) = 44
Hence, molecular mass of CO2 is 44 u.
