Answer: 0.0274 M
Explanation:-
The balanced chemical solution is:
According to the neutralization law,
where,
= molarity of 
solution = 0.117 M
= volume of solution = 23.4 ml
= molarity of 
solution = ?
= volume of solution = 100.0 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of ammonia in a solution will be 0.0274 M
B. sodium chloride changed the least; potassium nitrate changed the most.<span />
