Consider two 5.0-L containers, each filled with gas at $25^{\circ} \mathrm{C}$. One container is filled with helium and the other with $\mathrm{N}_{2}$. The density of gas in the two containers is the same. What is the relationship between the pressures in the two containers?

Key Concepts

Ideal Gas Law

The ideal gas law, expressed as PV = nRT, relates pressure, volume, temperature, and the number of moles of a gas. This fundamental equation provides the framework for understanding how changes in one of these variables affect the others in a system behaving like an ideal gas. It is a cornerstone of gas behavior in thermodynamics and is widely used to predict and relate the properties of gases under various conditions.

Relationship Between Density, Molar Mass, and Pressure

In the context of the ideal gas law, density (mass per unit volume) can be linked to pressure by considering the molar mass of the gas. Since the number of moles n can be expressed as the mass divided by the molar mass (n = mass/M), substituting this into the ideal gas law shows that pressure is directly proportional to the density and temperature, and inversely proportional to the molar mass (P = (density/M)RT). This relationship explains why, under conditions of equal density and temperature, gases with lower molar masses exert higher pressures.
