A sample of gas has a volume of 5.0 L when at a temperature of 320 K and a pressure of 2 atm. How many moles are there of this gas?

Consider this initial-rate data at a certain temperature for the reaction described by

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.

What is the measured amount of a product obtained from a chemical reaction?
