7. Gases

A sample of gas occupies a volume of 1.0 L at 25°C and constant pressure. What volume will the gas occupy at 100°C, assuming ideal gas behavior?

A 5.00 L tank contains 10.00 grams of oxygen gas (O_2) at a temperature of 350 K. What is the pressure in the tank in atmospheres (atm)? (Use R = 0.0821 L·atm·mol^{-1}·K^{-1})

Which of the following factors directly affect the behavior of the gas inside a hot air balloon according to the ideal gas law?

A 6.00 L tank contains 20.0 grams of nitrogen gas (N_2) at a temperature of 385 K. What is the pressure inside the tank? (Use R = 0.0821 L·atm·mol^{-1}·K^{-1})

A sample of gas occupies 100 in^3 at a pressure of 20 psi and a constant temperature. According to the ideal gas law, what would the volume of the gas be if the pressure is increased to 40 psi?

A sample of gas is collected over water at atmospheric pressure (patm = 1.00 atm). If the vapor pressure of water at the experimental temperature is 0.030 atm, what is the pressure of the dry gas (pgas)?
