A gas mixture contains 1.16 g N2 and 0.89 g O2 in a 1.49 L container at 16 degrees C. What is partial pressure of N2 & O2?
*I already know the mole fraction for N2 is 0.60, and 0.40 for O2. I just don't know where to go from here.

It appears to me that PV = nRT is the easiest thing to use.
You know V, R, and T and can calculate n.The only unknown is P.
