An unknown amount of water is mixed with
350 mL of a 6 M solution of NaOH solution. A 75 mL sample of the resulting solution is titrated to neutrality with 52.5 mL of 6 M HCl. Calculate the concentration of the diluted NaOH solution.

  1. HCl + NaOH ==> NaCl + H2O

    mols HCl = M x L = ?
    mols NaOH = mols HCl
    M NaOH = mols NaOH/L NaOH
    I believe that works out to be about 4.2M but check my work.
