A vessel contained N2, Ar, He, and Ne. The total pressure in the vessel was 1100 torr. The partial pressures of nitrogen, argon, and helium were 110, 250, and 400 torr, respectively. The partial pressure of neon in the vessel was torr. A) 420 B) 340 C) 200 D) 280 E) 760

Partial pressure Ne = 340 Torr

Option B

Explanation:

Gases contained in the vessel:

N₂, Ar, He, Ne

One of Dalton's law for gases determine this:

In a mixture of gases contained in a vessel, total pressure of the system must be the sum of partial pressure of each gas.

Total pressure = 1100 Torr

Let's replace:

Partial pressure N₂ + Partial pressure Ar + Partial pressure He + Partial pressure Ne  =  1100 Torr

Partial pressure Ne = 1100 Torr - Partial pressure N₂ - Partial pressure Ar  -Partial pressure He

Partial pressure Ne = 1100 Torr - 110 Torr - 250 Torr - 400 Torr

Partial pressure Ne = 340 Torr
