20. We combine 500 cm 1.2 mol/dm of acetic acid and 500 cm 0.5 mol/dm of sodium hydroxide solution. What is the pH of the created buffer solution? (4.59) 21. How will the pH of the buffer solution change in the previous problem if we add 40 cm 1 mol/dm of hydrochloric acid, or 50 cm 1 mol/dm² of sodium hydroxide solution? (4.70, 4.46)
Suppose 3.01 mol N_2 (g) occupies 22.5 dm^3 at 298.15K and expands to 66.5 dm^3 at that temperature. Calculate Delta G in joule for the process. Assume ideal gas behavior.
1)A flask containing oxygen has a volume of 3.5 dm at a pressure of 3.5 bar. Another flask with a volume of 5.0 dm contains neon at a pressure of 5.0 bar. These two flasks are connected and the two gases mix isothermally. Calculate the partial pressures of the two gases and the total pressure of the mixture. 2)Calculate the molar mass of an unknown gas with a mass of 0.462 grams that occupies a volume of 0.798 dm at...
