# Problem: A gas mixture contains 1.26 g N2 and 0.86 g O2 in a 1.56-L container at 18 oC.You want to reference (Pages 216 - 222) Section 5.6 while completing this problem.Calculate the partial pressure of N2.

###### FREE Expert Solution

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 N2 :

XN2 = 0.443

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
