A quantity of $\mathrm{N}_{2}$ occupies a volume of 1.0 $\mathrm{L}$ at 300 $\mathrm{K}$ and 1.0 $\mathrm{atm}$ . The gas expands to a volume of 3.0 $\mathrm{L}$ as the result of a change in both temperature and pressure. Find the density of the gas at these new conditions.

Key Concepts

Ideal Gas Law

The Ideal Gas Law (PV = nRT) relates the pressure, volume, temperature, and number of moles of a gas. It is a fundamental equation in thermodynamics that enables the determination of one state variable when the others are known. This law is essential for understanding the behavior of gases under various conditions and is widely applied to problems involving gas expansion or compression.

Gas Density

Gas density is defined as the mass of gas per unit volume. In the context of the Ideal Gas Law, density can be expressed in a form that incorporates pressure, temperature, and the molar mass of the gas. This relationship (often written as ? = PM/(RT)) is crucial for linking macroscopic conditions to the microscopic properties of a gas, enabling the calculation of density in varying conditions.

Molar Mass

Molar mass is the mass of one mole of a substance and serves as a bridge between the number of moles (from the Ideal Gas Law) and the mass of a gas sample. It is a key parameter when converting the amount of substance in moles to a mass basis, which is necessary for calculating the density of a gas from its pressure, volume, and temperature data.
