AP Chemistry Gas Law Practice Name ___________________________ Date _______________ Period _____ apgasprac0809.doc 1. Given the following equation; Na (s) + O 2(g) Na 2 O (s) How many grams of Na are required to react with 2.5L of O 2 at 755 torr and 15 ° C? 2. An open-end manometer possesses a 20.4L reaction chamber. The complete combustion of a certain quantity of propane gas produces 13.203g of CO 2 gas and 7.2064g of water vapor. If the temperature of the chamber is 353.15K and the equilibrium mercury level is 11mm higher on the reaction side of the chamber, what is the atmospheric pressure in torr? 3. A sealed flask contains a gas with pressure P. If the number of moles of the gas is doubled, the absolute temperature is doubled and the volume of the container is quadrupled, what is the new pressure in terms of P? 4. In the unbalanced equation, NO (g) + O 2(g) NO 2(g) If 30g each of NO and O 2 are reacted to completion in a 10L sealed container at 20 ° C, what is the final pressure in the container? (NOTE: This is a limiting reagent problem!) 5.
