A balloon is filled to a volume of 7.00 x 10 2 mL at a temperature of 20.0 o C. The balloon is then cooled at constant pressure to a temperature of 1.00 x 10 2 K. What is the final volume of the balloon? 239 mL 10. Consider the following chemical equation:2NO2(g) N2O4(g)If 25.0 mL of NO2gas is completely converted to N2O4gas under the same conditions, what volume will the N2O4occupy? 11. Complete the following table for an ideal gas P(atm) V(L) n(mol) T 7.74 x 10 3 Pa 12.2 mL 3.81 x 10 -5 25 o C 179 atm 43.0 mL 0.421 mol 223 K 455 torr 3.6 L 4.4 x 10 -2 mol 331 o C 745 mm Hg 11.2 L 0.401 mol 61 o C 12. A person accidentally swallows a drop of liquid oxygen, O 2 (l), which has a density of 1.149 g/mL. Assuming the drop has a volume of 0.050 mL, what volume of gas will be produced in the person’s stomach at body temperature (37 o C) and a pressure of 1.0 atm? 46 mL 13. A bicycle tire is filled with air to a pressure of 100.psi at a temperature of 19 o C. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 o C. The volume of the tire increases by 4.0%. What is the new pressure in the bicycle tire? 109 psi 14. A container is filled with an ideal gas to a pressure of 40.0 atm at 0 o C. a. What will be the pressure in the container if it is heated to 45 o C? 46.6 atm b. At what temperature would the pressure be 1.50 x 10 2 atm? 1.02 x 10 3 K c. At what temperature would the pressure be 25.0 atm? 171 K 15. A compressed gas cylinder contains 1.00 x 10 3 g of argon gas. The pressure inside the cylinder is 2050. psi (pounds per square inch) at a temperature of 18 o C. How much gas remains in the cylinder if the pressure is decreased to 650.psi at a temperature of 26 o C? 309 g Ar remains
