We are asked to calculate the partial pressure of O2.
Molar mass O2 = 32.00 g/mol
Molar mass N2 = 28.02 g/mol
Calculate moles each:
Calculate mole fraction O2 :
XO2 = 0.557
Given:
R = 0.08206 L-atm/mol-K
T = 18 oC +273.15 = 291.15 K
V= 1.56 L
n = 0.070 mol
Calculate total pressure:
P = 1.07 atm
You want to reference (Pages 216 - 222) Section 5.6 while completing this problem.
