Consider 4.60 L of a gas at 365 mmHg and 20. ∘C . If the container is compressed to 3.00 Land the temperature is increased to 38 ∘C , what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cylinder.
Express your answer with the appropriate units.

Imagine that the gas shown in the simulation is an ideal gas such as helium. Notice that the final number of moles of gas is 1.00 mol for each experimental run. You can find the final volume of the gas using the y axis of the graph shown.
Consider an experimental run at 273 K where the initial number of moles (n1) is actually 1.00 mol, and the final number of moles (n2) is 2.00 mol. Use the simulation to find the volume (V1) of 1.00 mol of helium at 273 K, and calculate the final volume (V2).
Express the volume to three significant figures, and include the appropriate units.
