What is the concentration of HCl in a 250.0 mL sample of hydrochloric acid if 15.5 mL of 0.0100 M NaOH is needed to react with all the HCl?

  • chemistry -

    The equation shows the reaction to b 1:1; therefore, the dilution formula may be used.
    HCl + NaOH ==> NaCl + H2O
    mLsoln1 x Msoln1 = mLsoln2 x Msoln2.
