Concept explainers
Interpretation:
The volume of the system at STP is to be determined. Also, the partial pressure of each gas is to be determined.
Concept introduction:
The ideal gas equation for one mole gas is written as
P= pressure of the gas
V= volume of the gas
R= gas constant
T = temperature of the
Dalton’s law also says that the entire pressure of the system is equal to the sum of the partial pressure of individual ones.
Answer to Problem 63A
The volume of the mixture at STP is
The partial pressure of gases He, Ar, and Ne are
Explanation of Solution
Given information:
Standard temperature, (T) =
Initial temperature in K=
Standard pressure (P1) =
Mass of helium gas =
The Molar mass of Helium gas =
Mass of argon gas =
The Molar mass of argon gas =
Mass of neon gas =
The Molar mass of neon gas =
Calculation:
To find the number of moles of He, Ar, and Ne atom:
Number of moles of helium is
The number of moles of argon is
The number of moles of neon is
To find the volume of the given atoms
To find partial pressure of each gas:
For argon
For neon
The total volume is
