To determine the concentration of an EDTA solution (292.24 g/mol) , 0.471 g of Zn (65.38 g/mol) metal was used. The volume of EDTA solution needed to reach the endpoint was 25.34 mL. What was the concentration (in molarity) of the EDTA solution

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.
