Respuesta :
6.6 is the mole fraction of xe if the partial pressures of ne and ar are 2.10 and 4.50 atm, respectively.
Why is partial pressure called?
The idea of partial pressure is driven by the fact that each individual gas contributes to the overall pressure in a given proportion, which corresponds to its partial pressure. In order to characterize all the pieces, it is essentially equivalent to taking a % or proportion of the whole.
Briefing:
The total pressure is equal to the sum of the individual pressures, according to Dalton's law.
Ptotal = total pressure of gases = 12.20 atm
Pne = partial pressure of ne = 2.10 atm
Par = partial pressure of ar = 4.50 atm
Pxe = partial pressure of xe = ?
putting in the values we get:
12.20 = 2.10 + 4.50 + Pxe
Pxe = 5.6
We employ Dalton's law to determine the solution's vapor pressure, which is:
Ptotal = (Pxe + Xxe)
We are given:
Pxe = partial pressure of xenon = 5.6
Xxe = mole fraction of xenon = ?
Using the values in the aforementioned equation, we get:
12.20 = (5.60 * Xxe)
Xxe = 6.6
The mole fraction of Xe is 6.6 as a result.
