Answer to Problem 108A
The mole fraction of N2, O2 and Ar in the sampleare 0.804, 0.189 and 0.0072 respectively.
Explanation of Solution
Data given:
The solution contains N2 = 78.0%, O2 = 21.0%and Ar = 1.0%
Let assume, the total mass of the sample = 100 gm
So, the mass of N2 = 78.0 gm, O2 = 21.0 gm and Ar = 1.0 gm
(Note: Molecular weight of N2 = 28 gm/mol)
(Note: Molecular weight of O2 = 32 gm/mol)
(Note: Molecular weight of argon = 39.95 gm/mol)
