a.
Interpretation:The mass of Xe in the given room needs to be calculated.
Concept introduction: The expression relating the pressure, P, volume, V with number of moles, n and temperature, T of an ideal gas is:
Where R is Universal gas constant.
a.

Answer to Problem 121AE
Explanation of Solution
Given:
The volume of Xe in atmosphere =
The dimensions of room is 7.26 m by 8.80 m by 5.67 m.
The volume of the room is:
Converting volume from m3to L as:
The amount of Xe present in the atmosphere is:
So,
The amount of Xe present in the room is:
Now, the number of moles of Xe present in the room is determined using equation (1):
The values to be substituted are:
Now, the mass of Xe is determined using formula:
Rearranging as:
Molar mass of Xe is
Substituting the values:
Thus, the mass of Xe in the given room is
b.
Interpretation: The number of Xe atoms inhaled in each breath needs to be calculated when the volume of air taken by a person is about 2 L.
Concept introduction: The expression relating the pressure, P, volume, V with number of moles, n and temperature, T of an ideal gas is:
