Chem 10 Class ExamplesGas Laws1. When a 1.500 L balloon filled with carbon dioxide gas at 22.0 C is heated, the balloon expands to 1750. mL. What is the new gas temperature in the balloon, in C? What is the overall temperature change that occurred? Assume P and n are constant.2. A 400. cm3 aerosol can contains compressed air at a pressure of 5.20 atm. When all of this air is “sprayed” into a plastic bag, the bag inflates to 2.14 L. Calculate the air pressure in the bag, in torr. Assume T and n are constant.3. 0.477 moles of dinitrogen monoxide gas fills a balloon to a volume of 14.8 L. Some of this gas then leaks out, and the balloon volume falls to 10.1 L. What mass of gas leaked out? Assume P and T are constant. 4. A 17 oz sealed flask is filled with hydrogen gas to a pressure of 974 mm Hg at 31 C. The flask is then placed in a container of liquid nitrogen, with a temperature of 77 K. Calculate the gas pressure in the flask at this new temperature. Assume V and n are constant.5. At 25.0 C, a balloon is filled with helium gas to 15.0 m3 and 740. torr. The balloon is released and rises to an altitude of 5000 m, where the temperature is -23.0 C and the pressure is 0.487 atm. Calculate the balloon volume at this altitude, in m3. Assume n is constant.Ideal Gas Law6. At 22 C, 0.891 grams of argon gas are introduced into an evacuated, sealed 250.0 mL flask. What is the gas pressure in the flask, in atm?7. A balloon is inflated with 2.67 grams of chlorine gas at 273 K. If the gas pressure exerted is 1.34 atm, calculate the gas density (in g/L) in the balloon.8. An unknown gas exerts a pressure of 1.06 atm in a 112 mL cylinder at 298 K. If the mass of the gas is 0.136 g, calculate the MM of the gas.STP and Molar Volume9. Calculate the volume of 0.392 moles of hydrogen gas at STP.10. Calculate the mass (in grams) of 4.11 L of sulfur trioxide gas at STP.Gas Stoichiometry11. Consider the reaction: 2 Al (s) + 3 H2SO4 (aq) Al2(SO4)3 (aq) + 3 H2 (g)Suppose that 10.0 grams of aluminum reacts completely with excess sulfuric acid. What volume of hydrogen gas (in L) will be collected at 0.787 atm and 310. K?12. Consider the reaction: 2 C6H14 (l) + 19 O2 (g) 12 CO2 (g) + 14 H2O (l)What mass (in g) of C6H14 is required to react completely with 2.88 L of oxygen gas at STP?13. Consider the reaction: 2 NaHCO3 (s) Na2CO3 (s) + H2O (l) + CO2 (g)When 2.65 grams of NaHCO3 are decomposed, all the CO2 gas generated is collected into a 150.0 mL flask at 298 K. Calculate the gas pressure in the flask (in atm).14. Consider the reaction: 3 O2 (g) 2 O3 (g)If 4.82 L of O2 are completely converted to O3 at constant temperature and pressure, what volume (in L) of O3 is
