Gas Law Calculations Final and Initial State Problems A gas often undergoes a change from an initial to a final state. Example : Consider a sample of gas at 25° C and 1.000 atm [ initial state, state 1 ]. What is the pressure if the gas is heated to 100° C at constant volume [ final state, state 2 ]? Using the ideal gas law, and remembering that n = const, V = const (and, of course R = const), we find that Initial state: p 1 V = nRT Final state: 2

Example: (MH5, Example 5.2) A 250 mL flask, open to the atmosphere, contains 0.0110 mol of air at 0° C, on heating, part of the air escapes; how much remains in the flask at 100° C ?

Unformatted text preview: C and 745 mm Hg. The syringe is transferred to a water bath maintained at 82 C, and the volume of the gas is increased by 8.0%. What is the pressure inside the syringe? Example : (MH5, Problem 5.32) Poisonous NO in smokestack emissions can be reduced by reaction with ammonia: 4 NH 3 (g) + 6 NO(g) 5 N 2 (g) + 6H 2 O(l) Assuming that all gases are at the same temperature and a yield of 100%, how many liters of N 2 are formed when 297 L of NO are treated with excess ammonia? Example : (Nov. 2006 exam, Q8) A mixture of Kr and Xe has a density of 2.50 g/L at a total pressure of 50.65 kPa and at 0 C. What is the partial pressure of Xe in the mixture?...
