A sample of a gas originally at 25°C and 1.00 atm pressure in a 2.5 L container is allowed to expand until the pressure is 0.85 atm and the temperature is 15°C. The final volume of the gas is:
The amount of neon gas that occupies 60.82 L at 31°C and 48.9 kPa is:
What is the volume occupied by 5.29 mol of a gas at 44°C and 105.7 kPa?
A 0.325 L flask filled with gas at 0.914 atm and 19°C contains:
1.22 x 10-4 mol
A gas occupies 355 mL at a pressure of 99.5 kPa and a temperature of 22°C. The pressure on the gas is subsequently increased by 10.0 kPa and the volume is dropped by 75 mL. What is the new temperature?
The pressure of a sample of 6.022 g CH4 in a 30.0 L vessel at 402 K is:
Which of the following accurately describes the particles of an ideal gas?
particles can undergo chemical reactions
particles have no mass or volume
particles will condense to a liquid when compressed and/or cooled
particles are affected by intermolecular forces at extremely high pressures
A container with an initial volume of 1.00 L is occupied by a gas at a pressure of 155 kPa at 25°C. By changing the pressure, the volume of the gas increases to 6.00 L as the temperature is simultaneously raised to 100.°C. What is the new pressure of the container?
A sample of 2.35 moles of helium gas occupies 57.9 L at 27.0°C and 1.00 atm. At 150.°C and 1.00 atm, the volume of this sample is:
If a sample of gas occupies 6.8 L at 376°C and 1.5 atm, what will be its volume at standard temperature and pressure (STP)?
