477.1 mg of KHP is dissolved in approximately 50 mL of de-ionized water in a 250 mL Erlymeyer flask and titrated with an NaOH solution. The titration required 25.31 mL to reach the phenolphthalein endpoint. The NaOH solution was also used to titrate 25.00 mL of a dilute HCl solution. The dilute HCl solution required 27.73 mL to reach the phenolphthalein endpoint. Determine the concentrations of the NaOH and the HCl solutions.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
