1. A gas has a volume of 800.0 mL at minus 23.00 C and 300.0 torr. What would the volume of the gas be at 227.0 C and 600.0 torr of pressure? 2. 500.0 liters of a gas are prepared at 700.0 mm Hg and 200.0 C. The gas is placed into a tank under high pressure. When the tank cools to 20.0 C, the pressure of the gas is 30.0 atm. What is the volume of the gas? 3. What is the final volume of a 400.0 mL gas sample that is subjected to a temperature change from 22.0 C to 30.0 C and a pressure change from 760.0 mm Hg to 360.0 mm Hg? 4. What is the volume of gas at 2.00 atm and 200.0 K if its original volume was 300.0 L at 0.250 atm and 400.0 K. 5. At conditions of 785.0 torr of pressure and 15.0 C temperature, a gas occupies a volume of 45.5 mL. What will be the volume of the same gas at 745.0 torr and 30.0 C? 6. A gas occupies a volume of 34.2 mL at a temperature of 15.0 C and a pressure of 800.0 torr. What will be the volume of this gas at standard conditions? 7. The volume of a gas originally at standard temperature and pressure was recorded as 488.8 mL. What volume would the same gas occupy when subjected to a pressure of 100.0 atm and temperature of minus 245.0 C?
