7. Gases

A real gas will behave most like an ideal gas under conditions of ________.

Using the ideal gas law, what is the pressure (in atm) in a 5.80 L container that contains 0.545 moles of oxygen gas at 22.0 °C?

According to the ideal gas law, by what factor does the temperature of a gas change if both its volume and pressure are doubled, assuming the amount of gas remains constant?

A 250.0 mL container holds nitrogen gas (N_2) at a pressure of 780 mm Hg and a temperature of 135 °C. Using the ideal gas law, how many molecules of N_2 are present in the container?

Which of the following best explains why it can be difficult to accurately measure the volume of a gas in a laboratory setting?

A sample of gas is contained in a 5.0 L vessel at a temperature of 373 K and a pressure of 203 kPa. Using the ideal gas law, how many moles of gas are present in the container? (Use R = 8.314 L·kPa·K^{-1}·mol^{-1})
