Section 14.3 The Ideal Gas Law
Objectives • Relate the amount of gas present to its pressure, temperature, and volume by using ideal gas law • Compare the properties of real an ideal gases
Key Terms • Ideal gas constant, R • Ideal gas law
Ideal Gas Law: • PV = nRT • n= number of moles • R is a constant
Real vs Ideal Gases • Ideal particles do not take up space; no intermolecular forces • Follows all gas laws always • Real Particles have some volume; some forces • Approximately follows laws
Finding molar mass • n = m/M • m is mass • M is molar mass • PV = mRT OR M = mRT M PV
