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 
<span>The periodic law states that the physical and chemical properties of elements are periodic functions of their "Atomic Numbers"
So, option B is your answer.
Hope this helps!

The enthalpy energy in condensation process is negative because it releases energy
The entropy in will also decreases .
Temperature affected this change because it will now create free energy if added with this result this is the condestion process
