MIXED GAS LAWS WORKSHEET 1) How many moles of gas occupy 98 L at a pressure of 2.8 atmospheres and a temperature of 292 K? 2) If 5.0 moles of O 2 and 3.0 moles of N 2 are placed in a 30.0 L tank at a temperature of 25 0 C, what will the pressure of the resulting mixture of gases be? 3) A balloon is filled with 35.0 L of helium in the morning when the temperature is 20.0 0 C. By noon the temperature has risen to 45.0 0 C. What is the new volume of the balloon? 4) A 35 L tank of oxygen is at 315 K with an internal pressure of 190 atmospheres. How many moles of gas does the tank contain?

5) A balloon that can hold 85 L of air is inflated with 3.5 moles of gas at a pressure of 1.0 atmosphere. What is the temperature in 0 C of the balloon? 6) CaCO 3 decomposes at 1200 0 C to form CO 2 gas and CaO. If 25 L of CO 2 are collected at 1200 0 C, what will the volume of this gas be after it cools to 25 0 C? 7) A helium balloon with an internal pressure of 1.00 atm and a volume of 4.50 L at 20.0 0 C is released. What volume will the balloon occupy at an altitude where the pressure is 0.600 atm and the temperature is –20.0 0 C? 8) There are 135 L of gas in a container at a temperature of 260 0 C. If the gas was cooled until the volume decreased to 75 L, what would the temperature of the gas be?
A 75 L container holds 62 moles of gas at a temperature of 215 0 C. What is the pressure in atmospheres inside the container? 10) 6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume is 3.5 L. What is the new pressure inside the piston? 11) A gas canister can tolerate internal pressures up to 210 atmospheres. If a 2.0 L canister holding 3.5 moles of gas is heated to 1350 0 C, will the canister explode? 12)
