construct the balance equation for NaOH and HCl reaction
obtain a mole ration i.e. 1:1
determine the actual mole of NaOH reacting using c=n/v where c is 0.1 and v is 54
use this mole to find the concentration of HCl using c=n/v
hope that helps
If it takes 54 mL of 0.1 M NaOH to neutralize 125 mL of an HCI solution, what is the concentration of the HCI?
