Answer:
0.55 atm
Explanation:
According to Dalton's law of partial pressures,
The total pressure is the summation of the partial pressures of individual gases in a sample of non-reactive gases.
Since Neon and Argon are noble gases, they do not react with each other. So we can apply Dalton's partial pressure law.
P total = P Ar + P Ne
2.39 atm = P Ar+ 1.84 atm
P Ar = 2.39 atm - 1.84 atm
= 0.55 atm
