In all the fields of science (and also in economy, politics, moral, medicine, etc.) the ideal state is only a word. The ideal doesn't exist but it is very necessary to elaborate valid theories. In conclusion one can say that xenon is still a (quasi)ideal gas.

Xenon deviates from ideal gas behavior due to its relatively large atomic/molecular size and interactions between xenon atoms. At higher pressures and lower temperatures, these interactions become more significant, causing xenon to deviate from ideal gas behavior. These deviations are better described by the Van der Waals equation or other equations of state.
A real gas behaves most like an ideal gas when it is at low pressure and high temperature.
A real gas behaves most like an ideal gas at high temperatures and low pressures.
The ideal conditions for a gas mixture containing propane to behave like an ideal gas when mixed with air are when the temperature is high, the pressure is low, and the molecules are far apart from each other. This allows the gas molecules to move freely and independently, similar to how an ideal gas behaves.
The volume of a gas like xenon can be calculated using the ideal gas law equation: PV = nRT. Given the mass of xenon, you would first need to convert it to moles using the molar mass of xenon (131.3 g/mol). Then, using the ideal gas constant (R) and the temperature and pressure of the gas, you can calculate the volume.
Two gases on the periodic table that behave like ideal gases are helium (He) and neon (Ne). Ideal gases follow the ideal gas law, which assumes that the gas particles are point masses and do not interact with each other. Helium and neon have low atomic masses and weak intermolecular forces, making their behavior close to ideal in most conditions.
