Answer #1

                   HCl + H2O ------> H3O+ + Cl-

                   0.0362M             0.0362M

                  [H3O+]   = [HCl]

                 [H3O+]   = 0.0362M

                 [OH-]     = Kw/[H3O+]

                              = 1*10-14/0.0362

                                = 2.7*10-13 M
