A 11.0 gram sample of nitrogen gas has a volume of 972 milliliters at a pressure of 2.81 atm. The temperature of the N2 gas sample is.
it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.338 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibri..
