A rubber stopper weighing 8.554 grams displaces 7.0 mL of water. To the nearest tenth of a gram per mL, what is the density of the ſubber stopper? (You do not need to include units in your answer.)​

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
