Question

1) A mixture of neon and xenon gases, at a total pressure of 745 mm Hg, contains 1.62 grams of neon and 17.9 grams of xenon. What is the partial pressure of each gas in the mixture? PNe =.................. mm Hg ? PXe = .................... mm Hg?

2) A mixture of neon and oxygen gases contains neon at a partial pressure of 363 mm Hg and oxygen at a partial pressure of 610 mm Hg. What is the mole fraction of each gas in the mixture?
X_Ne =...........? , X_O2 =.............?

3)What volume is occupied by a 1.85 mol sample of neon gas at a temperature of 0 °C and a pressure of 1 atm?
=..............L ?

Answer 1

= 0.0803 mol Moly of Neon men = 1.62g 1 M.W 20.18 g/mol Moles of xenon: 17.9 g = 131.2 g/mol 0.136 mol PNC: XneX Total pressure (0.0803 )* 745 10.136 +0.0803 Pne Pixe: = [216 moning 745-276 - 1469 ] monty
