1.) A scuba tank has a volume of 10.3 L and a pressure of 19,300 kPa. If the gas is transferred to a 50.0 L container, what is it's new pressure? 2.) When a piston with a volume of 35.0 mL is heated from 25.0°C to 323°C, it expands. What is its new volume at the higher temperature? 3.) The Kelvin temperature of a sample of NH3 gas holding 650. cm3 is suddenly doubled. What is the new volume? 4.) If a gas is cooled from 315 K to 231 K, what was its initial pressure if its final pressure is 625 torr? 5.) A gas tank has a volume of 28.1 m3 and a pressure of 18.4 atm. The temperature of the gas is 32°C. What is the Celsius temperature when the gas is put in an 11.2 m3 tank with a pressure of 22.7 atm? 6.)If 3.25 moles of Ar occupies 100.L at a certain temperature and pressure, what volume does 14.15 moles of Ar occupy? 7.) If 4.0 grams of He occupies 22.4 L at 0.00°C and 1.00 atm pressure, what volume does 3.0 grams of He occupy under the same conditions? 8.) A scuba tank has a pressure of 195 atm at a temperature of 10.0°C. The volume of the tank is 350. L. How many moles of air are in the tank? 9.) A tank of oxygen has a volume of 1650 L. The temperature of the gas inside is 35°C. If there are 9750 moles of oxygen in the tank, what is it's pressure in kPa? 10.) Calculate the volume of a CO2 cartridge that has a pressure of 5860 kPa at a temperature of 21°C. The cartridge contains 0.273 moles of CO2. 11.) You have 25.0 grams of an unknown gas in a 13.5 L container at a pressure of 202 kPa and 0.00°C. What is its molar mass?
