Calculate the density of the block below, if it has a mass of 27 g using the correct number of significant figures. 5 cm 10 cm 20 cm 02.7 x 104 g/cm3 0 0.027 g/cm² 37.04 g/cm3 O 35 g/cm3

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.
