Given the two reactions 1. H₂S(aq) HS¯(aq) + H+ (aq), K₁=9.73x10-8, and 2. HS (aq) = S2-(aq) + H+ (aq), K₂ = 1.47x10-19,

Question

Given the two reactions 1. H₂S(aq)<-> HS¯(aq) + H+ (aq), K₁=9.73x10-8, and 2. HS (aq) = <->S2-(aq) + H+ (aq), K₂ = 1.47x10-19, what is the equilibrium constant Kfinal for the following reaction? S2 (aq) + 2H+ (aq) <-> H₂S(aq) Enter your answer numerically.
