Answer: 0.132 M
Step-by-step explanation:
According to the neutralization law,

where,
= molarity of
solution = ?
= volume of
solution = 0.100 L = 100 ml (1L=1000ml)
= molarity of
solution = 0.200 M
= volume of
solution = 32.9 ml
= valency of
= 1
= valency of
= 2


Therefore, the concentration of
solution is 0.132 M
