Answer:
The concentration of KBr is 
Explanation:
From the question we are told that
The mass of KBr is 
The molar mass of KBr is 
Volume of water is 
This implies that the volume of the solution is 
The number of moles of KBr is
Substituting values
The concentration of KBr is mathematically represented as
Bonds between atoms break and new ones form and energy is either given out or taken in
