Question

A cylinder of a gas mixture used for calibration of air analyzers in laboratories contains 10.61% carbon dioxide, 24.89% water vapor, and the remainder xenon at a total pressure of 155.66 atm. What is the partial pressure of each component of this gas? (The percentages given indicate the percent of the total pressure that is due to each component.)

_______atm carbon dioxide

________atm water vapor

_________atm xenon

Answer 1

P_total = 155.66 atm

P_CO2 = 0.1061 x 155.66 atm = 16.52 atm

P_H2O = 0.2489 x 155.66 atm = 38.74 atm

P_Xe = 155.66 - 16.52 - 38.74 = 100.4 atm
