Gas Stoichiometry

Gas Stoichiometry. STP = standard temperature and pressure T = 0 o C = 273 K, P = 1 atm at STP the volume of 1 mole of gas = 22.42 L (22.42 L/mole) Ex - Find the number of moles of 2.0 L of CO 2 at STP. Ex - The industrial synthesis of nitric acid involves the reaction:

  1. Gas Stoichiometry

  2. STP = standard temperature and pressure T = 0o C = 273 K, P = 1 atm at STP the volume of 1 mole of gas = 22.42 L (22.42 L/mole) Ex - Find the number of moles of 2.0 L of CO2 at STP.

  3. Ex - The industrial synthesis of nitric acid involves the reaction: 3 NO2(g) + H2O(l) --> 2 HNO3(aq) + NO(g) If 450. L of NO2 at 5.00 atm and 295 K react, how many moles of nitric acid are formed?

  4. Ex - What is the density of CO2 gas at 745 mm Hg and 65oC?

  5. Dalton's Law of Partial Pressures PT = P1 + P2 +P3 +.... Mole Fraction (X) = n1/ntotal it also equals P1/PT

  6. If a gas is collected over water, the evaporated water contributes to the total pressure. To correct for this, subtract the vapor pressure of water from the total pressure of the collected gas.

  7. A student prepares a sample of hydrogen gas by electrolyzing water at 25oC. She collects 152 mL of H2 at a total pressure of 758 mm Hg. Given that the vapor pressure of water at 25oC is 23.76 mm Hg, calculate a. the partial pressure of hydrogen b. the number of moles of hydrogen collected
