A mixture of argon and xenon gases, in a 7.39 L flask at 65 °C, contains 3.89 grams of argon and 16.4 grams of xenon. The partial pressure of xenon in the flask is ____ atm and the total pressure in the flask is ____ atm
Solutions
Expert Solution
no of moles of Ar = W/G.A.Wt
= 3.89/40 = 0.09725 moles
no of moles of Xe = W/G.A.Wt
= 16.4/131.29 = 0.1249 moles
total no of moles n = 0.09725+0.1249 = 0.22215moles
T = 65+273 = 338K
V = 7.39L
PV = nRT
P = nRT/V
= 0.22215*0.0821*338/7.39 = 0.834atm
