A closed container of volume $0.02 \mathrm{~m}^{3}$ contains a mixture of Neon and Argon gases at temperature $27^{\circ} \mathrm{C}$ and pressure $10^{5} \mathrm{~N} / \mathrm{m}^{2} .$ The total mass of the mixture is 28 gram. If the gram molecular weights are 20 for Ncon and 40 for Argon, find the mass ol the individual gases in tho containcr, assuming them to be ideal $(R=8.314 \mathrm{~J} / \mathrm{mol} \mathrm{e}-\mathrm{K})$.

Key Concepts

Ideal Gas Law

The ideal gas law, expressed as PV = nRT, relates the pressure, volume, number of moles, and temperature of a gas. This concept is essential because it allows us to compute the total number of moles in a gas mixture by knowing the macroscopic properties, and it forms the foundation for many calculations involving gases under the ideal gas approximation.

Molar Mass and Mole Concept

The mole concept connects the mass of a substance to the number of molecules or particles through its molar mass. By using the molar mass, it is possible to convert between the mass of individual gases and their corresponding mole quantities, enabling calculations in gas mixtures and chemical reactions.

Dalton's Law of Partial Pressures

Dalton's law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each constituent gas. This concept is crucial when dealing with gas mixtures as it allows one to determine the contribution of each gas component based on its mole fraction, thereby enabling separate calculation of individual gas properties within the mixture.

System of Equations in Gas Mixtures

When dealing with mixtures of gases, setting up a system of equations that accounts for both the total mass and the total number of moles is essential. This involves using the relationships provided by the ideal gas law, the mole concept, and Dalton's law to link the individual masses, moles, and molar masses of the gases. Solving these equations simultaneously allows for the determination of the mass distribution among the gases in the mixture.
