Expert Solution

no of moles of HClo2 = Molarity * volume in L

                                       = 0.34*1 = 0.34 moles

                      HClO2 + NaF ----------> NaClO2 + H2O

       I                0.34     0.15                      0

      C              -0.15    -0.15                    0.15

      E                0.19       0                        0.15

                [HClO2] = 0.19moles

                [HClO2]   = 0.19/1 = 0.19 M >>>>> answer
