At 25 degrees C, the equilibrium constant Ka, for hydrofluoric acid is 7.2 x 10^-4 mol dm^-3 and the equilibrium concentratration of HF(aq) is 0.01 mol dm^-3. Calculate the equilibrium concentrations of H+ (aq) and F- (aq) and hence its ph of the acide solution. Please show your working in full and english so a simple person can understand. this should be done to 2 sig figs.

HF + H2O --> F- + H3O
