single covalent bond. They are much harder to break.
Answer:
Molar mass of bromine is equal to
Explanation:
The molar mass of HBr is equal to the sum of atomic weight of Bromine.
Atomic Weight of hydrogen is equal to
Atomic Weight of Bromine is equal to
Molar mass of Bromine
= Atomic Weight of hydrogen + Atomic Weight of Bromine
Molar mass of Bromine
The answer would 5.66 x 10 power of 24
