A sample of gas contains 4.44 moles of oxygen, 1.35 moles of nitrogen, and 1.13 moles of carbon dioxide. If the total pressure is 4.14 atm, what is the partial pressure of the oxygen in atm?

Solutions

Expert Solution

no of moles of O2 n_O2 = 4.44 moles

no of moles of N2 n_N2 = 1.35 moles

no of moles of CO2 n_Co2 = 1.13 moles

mole fraction of X_O2 = n_O2 /n_O2 + n_N2 + n_Co2

= 4.44/4.44+1.35+1.13

= 4.44/6.92 = 0.64

partial pressure of O2 P_O2 = X_O2 *P_T

= 0.64*4.14 = 2.6496atm
