Question
Calculate the molecular mass of hydrogen bromide (HBr). (Atomic masses : H = 1 u ; Br = 80 u)
Advertisements
Solution
Given:
Atomic mass of H = 1 u
Atomic mass of Br = 80 u
Therefore, molecular mass of HBr can be calculated as follows:
(1 × 1) + (1 × 80) = 81
Hence, molecular mass of hydrogen bromide is 81 u.
