Ideal Gas Law PV = nRT,  = mass/vol, so PM = RT R = 0.08206 L-atm-mol-1-K-1 (Table 1.5 has R in lots of combinations of units)

Unformatted text preview: At STP (P=1 atm, T=25oC=298K), this gives molar volume of any ideal gas as V/n = RT/1 ≈ 24.466 L/mol Ideal Gas Law • MW = molecular weight (actually, mass) • units: grams/mole (g/mol) • mol is sometimes referred to as “gmol” Ideal Gas Law • To treat “air” as an ideal gas, we need its molecular weight • Air is approximately 78% N2, 21% O2, 1% Ar • Assuming N2, O2, and Ar are ideal gases, MW of air = 0.78(28) + 0.21(32) + 0.01(40) = 28.964 ≈ 29 (g/mol, kg/kmol, lb/lbmol)...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
