How do i fill out an ICE chart when i am only given an initial concentration of one reactants and an equilibrium of another reaction?

inital 0.045 HNO2(aq)
Equilibrium 0.0043 H3O+(aq)
NO2(aq) - no information

my first thought was to sqaure root .0043 mol/l by 10 to find the change in H3O.

also should intial of H3O and NO2 be zero?

See your post above.
