Answer: 0.123 M
Explanation:
According to the neutralization law:
where,
= molarity of 
solution = ?
= volume of solution = 15.00 ml
= molarity of 
solution = 0.100 M
= volume of solution = 18.44 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of the unknown HBr solution is 0.123 M
