Video transcript

Hi everyone here we have a question telling us that Sean below is a graph of density overpressure versus pressure at 10°C, which should be constant at all pressures for an ideal gas. Explain why density overpressure versus pressure is not a straight line. So real gasses have a finite volume, which means density will vary. They experience attractive inter molecular forces, which means the pressure exerted will vary, and that is why when it comes to a real gas density over pressure will vary with pressure. Thank you for watching. Bye.

An 8.40-g sample of argon and an unknown mass of H2 are mixed in a flask at room temperature. The partial pressure of the argon is 44.0 kPa, and that of the hydrogen is 57.33 kPa. What is the mass of the hydrogen?

Textbook Question
An ideal gas at a pressure of 152 kPa is contained in a bulb of unknown volume. A stopcock is used to connect this bulb with a previously evacuated bulb that has a volume of 0.800 L as shown here. When the stopcock is opened, the gas expands into the empty bulb. If the temperature is held constant during this process and the final pressure is 92.66 kPa, what is the volume of the bulb that was originally filled with gas?
