2. A sample of gas occupies a volume of 10.5 L at 700 mmHg and 100°C. What would the new pressure be, in atm, if the volume decreased to 8.0 L and the temperature to 250°C?

If the density of a gas is 1.2 g/L at 745 mmHg and 23.5◦C, what is the molar mass of the gas?

A gas occupies a volume of 4.50 L at 760.0 mmHg at a temperature of 25°C. What would be the new volume at 200.0 mmHg, assuming temperature and number of moles are held constant?

If a sample of oxygen gas occupies 4.8 L at 199.0 °C and 2158 mmHg, what pressure in atm will it be at if it decreases to a volume of 1.6 L at a temperature of 98.2 °C?

45.0 L of an ideal gas at 288 K and 3.50 atm are heated to 373 K with a new pressure of 8.20 atm. What is the new volume (in L)?

A sample of hydrogen gas has a volume of 6.04 L at 47°C and 1.32 atm. What would be the volume of this gas sample at STP? (STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP = 0°C, 1 bar, where the molar volume = 22.7 L/mol.) Volume =  L

4. In a laparoscopic surgery, carbon dioxide gas is used to inflate the abdomen to separate the internal organs and the abdominal wall. If the CO2 injected into the abdomen produces a pressure of 17 mmHg and a volume of 2.9 L at 26°C, how many moles of CO2 were used? How many grams? 5. What is the total pressure, in millimeters of mercury, of a gas mixture containing krypton gas at 0.45 atm and neon gas at 650 mmHg?

What temperature (in °C) did an ideal gas shift to if it was initially at -22.00 °C at 4.620 atm and 35.00 L and the pressure was changed to 8.710 atm and the volume changed to 15.00 L?

A sample of helium gas occupies a volume of 6.79 L at 60.0°C and 391 torr. If the volume of the gas sample is decreased to 4.61 L, while its temperature is increased to 131.0°C, the resulting gas pressure will be torr.

A gas sample occupies a volume of 7.85 L at 23 degrees Celsius and exerts a pressure of 3.5 atm. What will the pressure change to if the volume is decreased to 5.00 L and the temperature increases to 35 degrees Celsius?
