Chapter 2: Problem 126

Two equal-volume balloons contain the same number of atoms. One contains helium and one contains argon. Comment on the relative densities of the gases in these balloons.

Short Answer

Expert verified

Given the same volume and number of atoms, the balloon containing Argon has a higher density than the balloon containing Helium due to the higher atomic mass of Argon.

Step by step solution

Understand Density and its Relationship with Mass and Volume

For starters, let's understand the concept of Density. Density is defined as mass per unit volume, often represented by the Greek letter rho \(\rho\). Mathematically, \(\rho = \frac{m}{V}\), where 'm' is the mass and 'V' is the volume.

Understand the Context of Problem

We are given that Helium and Argon balloons have identical volumes and the same number of atoms. It's also important to note that the atomic mass of Argon (approximately 40 units) is much higher than that of Helium (approximately 4 units).

Apply Knowledge

Considering the equation of density, the volumes of the two balloons are the same, and each contains the same number of atoms. So, the determining factor here for density is the mass of the gases. Because Argon has a higher atomic mass than Helium, the mass of Argon in the balloon will be greater than the mass of Helium, given the number of atoms are same. So, the density of Argon in the balloon would be greater than that of the Helium.
