The pressure of the xenon gas will increase if the number of moles increases because as more molecules are in the container, the molecules hit the container of the wall more often (option C).
<h3>What is an ideal gas?</h3>
Ideal gas is a hypothetical gas, whose molecules exhibit no interaction, and undergo elastic collision with each other and with the walls of the container.
According to this question, a 1.81 mol sample of Xenon gas is confined in a 42.6 liter container at 14.1 °C. If the amount of gas is increased to 2.72 mol, holding the volume and temperature constant, the pressure will increase.
An increase in the number of gas molecules, while container volume stays constant causes the pressure to increase due to the fact that the molecules will collide more with the walls of the container.
