Question
Calculate the molecular masses of the following :
Chlorine, Cl2
(Atomic masses : H = 1 u ; O = 16 u ; Cl = 35.5 u ; N = 14 u ; C = 12 u)
Solution
Given:
Atomic mass of Cl = 35.5 u
Therefore, molecular mass of Cl2 can be calculated as follows:
35.5 × 2 = 71
Hence, molecular mass of Cl2 is 71 u.
