Question
Calculate the molecular masses of the following :
Ammonia, NH3
(Atomic masses : H = 1 u ; O = 16 u ; Cl = 35.5 u ; N = 14 u ; C = 12 u)
Advertisements
Solution
Given:
Atomic mass of N = 14 u
Atomic mass of H = 1 u
Therefore, molecular mass of NH3 can be calculated as follows:
(1 × 14) + (3 × 1) = 17
Hence, molecular mass of NH3 is 17 u.
