a.
To determine: If the statement comparing the pressure of helium and neon is true or false.
Explanation of Solution
As per the ideal gas equation:
According to equation (2), the pressure P of a gas is inversely proportional to its molar mass. The molar mass for and that of . Therefore, will have a higher pressure than . Hence, the given statement is true.
b.
To determine:
If the statement comparing the densities of helium and neon is true or false
Explanation of Solution
We know that, the density is given as:
Since, the mass and volume of both the gases are same. Therefore, ratio of mass and volume that is the density of both the gases are same.
Under the given conditions, will have a higher pressure than . However, the density of and are same.
