in a titration 5.0 mL of a 2.0 M NaOH(aq) solution exactly neutralizes 10.0 mL of an HCI(aq) solution. What is the concentration of the HCI(aq) solution?

Volume of base(NaOH)= Vb =5 mL
Concentration of base(NaOH)= Mb =2 M
Volume of acid(HCl)= Va =10 mL
Concentration of acid(HCl)= Ma = ?
Now,
                                    Ma*Va = Mb*Vb
                                   Ma*(10) = (2)*(5)

                                   Ma= 1M
