A 27.00mL sample of an H2SO4 solution of unknown concentration is titrated with a 0.1422M KOH solution. A volume of 40.22mL of KOH was required to reach the equivalence point.

What is the concentration of the unknown H2SO4 solution?

Any help would be greatly appreciated. (:

    H2SO4 + 2KOH ==> K2SO4 + 2H2O
    mols KOH = M x L = ?
    Convert mols KOH to mols H2SO4 using the coefficients in the balanced equation.
    Then M H2SO4 = mols H2SO4/L H2SO4
