1) If you have a 1.0L sample of He gas and a 1.0L sample of Ar gas both at 25°C and 1atm a) Do the atoms in the He sample have the same average kinetic energy as the atoms in the Ar gas sample? b) Do the atoms in the He gas sample have the same average velocity as the atoms in the Ar gas sample? c) Which gas sample has the faster rate of effusion? 2) Conversions: (K=°C +273) (1atm = 760 mmHg) (1atm= 14.7 psi) (1atm=760 torr) (1atm=101325 Pa) 37°C to K 4500mmHg to atm 850 torr to atm 60 psi to atm 3) A sample of gas has an initial volume of 5.6L at a pressure of 735mmHg. If the volume of the gas is increased to 9.4L what is the pressure? 4) A 3.55 L sample of gas is warmed from 22°C to 87°C. What is the volume at the final temperature? 5) A balloon contains 0.155 moles of gas and has a volume of 2.45L. If an additional 0.255 moles of gas are added to the balloon (at the same temperature and pressure) what is the final volume? 6) What is the pressure of a 15.0L cylinder filled with 66.5g of oxygen gas at a temperature of 302K? 7) What is the volume of 55.7g of Ne gas at STP? 8) What is the density (in g/L) of H₂ gas at 20.0°C and a pressure of 1655 psi? 9) Consider the following reaction: C(s) + H₂O(g) → CO(g) + H₂(g) How many liters of H₂ gas are formed from the complete reaction of 15.7 g of C at a pressure of 1.0atm and a temperature of 355K? 10) A gas mixture contains each of the following gasses at the indicated partial pressure: N₂ 215 torr, O₂ 102 torr and He 107 torr. What is the total pressure of the mixture? What is the mole fraction of each gas in a 1.35L of vessel at 25.°0C?
