Question

Calculate the molecular masses of the following :

1. Hydrogen, H₂

(Atomic masses : H = 1 u ; O = 16 u ; Cl = 35.5 u ; N = 14 u ; C = 12 u)

Answer 1

1. Given:
   Atomic mass of H = 1 u
   Therefore, molecular mass of H₂ can be calculated as follows:
   1 × 2 = 2
   Hence, molecular mass of H₂ is 2 u.
