Question
Calculate the molecular masses of the following :
Oxygen, O2
(Atomic masses : H = 1 u ; O = 16 u ; Cl = 35.5 u ; N = 14 u ; C = 12 u)
Advertisements
Solution
Given:
Atomic mass of O = 16 u
Therefore, molecular mass of O2 can be calculated as follows:
16 × 2 = 32
Hence, molecular mass of O2 is 32 u.
