A chemist must prepare of aqueous nickel(II) chloride working solution. He'll do this by pouring out some aqueous nickel(II) chloride stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in of the nickel(II) chloride stock solution that the chemist should pour out. Round your answer to significant digits.

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.
