Answer:

102.6 mL

Explanation:

The reaction that takes place is:

  • NaOH + HCl → NaCl + H₂O

First we calculate how many NaOH moles are there in 50.00 mL of a 0.8000 M solution:

  • 0.8000 M * 50.00 mL = 40 mmol NaOH

Then we convert NaOH moles into HCl moles:

  • 40 mmol NaOH * [tex]\frac{1mmolHCl}{1mmolNaOH}[/tex] = 40 mmol HCl

Finally we calculate the volume of a 0.3900 M solution would contain 40 milimoles:

  • 40 mmol / 0.3900 M = 102.6 mL
