Physics 212 Lecture: "Avagadro's Number, Moles, and the Ideal Gas Law". Jan 12, 1998

• It is convenient to express the mass of atoms and molecules in atomic mass units
• One mole of a substance has the a mass (in grams) equal to the mass (in atomic mass units) of its molecules
• One mole of a substance contains Avagadro's number of molecules: N(A) = 6.022x10^23
• The ideal gas law relates pressure, volume, temperature and number of moles for a gas

This lecture discusses material in Chapter 14 of Cutnell and Johnson.
