A sample of gas occupies a volume of 66.0 mL. As it expands, it
does 148.9 J of work on its surroundings at a constant pressure of
783 torr. What is the final volume of the gas?
A sample of an ideal gas occupies a volume of 25.0 liters at a
pressure of 1.20 atm and a temperature of 75 degrees C. How many
moles of gas are present in the container?
A sample of ideal gas at room temperature occupies a volume of
22.0 L at a pressure of 482 torr . If the pressure changes to 2410
torr , with no change in the temperature or moles of gas, what is
the new volume, V2?
1. A sample of methane gas that occupies a volume
of 12.8 L at a temperature of 0 °C and a pressure
of 1 atm contains ________ moles of gas.
2. A mixture of argon and
helium gases, in a 9.49 L flask
at 39 °C, contains 6.75 grams of
argon and 1.61 grams of
helium. The partial pressure of
helium in the flask is _______ atm and the total
pressure in the flask is _______ atm.
Air that occupies a volume of 0.142m3 at a gauge pressure of
103kPa, expands isothermally to zero gauge pressure and then is
cooled to constant pressure until it reaches its initial volume.
Calculate the work done on the gas.
Answer: -5.74 kJ

1. A sample of ideal gas at room temperature occupies a volume
of 38.0 L at a pressure of 512 torr . If the pressure changes to
2560 torr , with no change in the temperature or moles of gas, what
is the new volume, V2?
Express your answer with the appropriate units.
V2 =
2. If the volume of the original sample in Part A (P1 =
512 torr , V1 = 38.0 L ) changes to 51.0 L...
A sample of oxygen gas occupies a volume of 9.30 L at 52.0°C and
0.790 atm. If it is desired to increase the volume of the gas
sample to 11.0 L, while decreasing its pressure to 0.569 atm, the
temperature of the gas sample at the new volume and pressure must
be °C.
