1. Chapter 10: Gases STP *standard temp and pressure temp= 273.15K, 0ºC pressure= 101.3kPa, 1atm, 760mmHg, 760torr Problems Convert: a) 0.357atm  torr b) 147.2kPa  torr c) 1.32atm  kPa

2. Gas Laws Variables: P = pressure V= volume (L) T = temp (K) n = amount of gas (mol) *R = ideal gas constant

4. Avogadro’s hypothesis- equal volume of gases at STP contain equal number of particles *22.4L of any gas @ 273K has 1mol of gas

5. Ideal Gas Equation PV = nRT *ideal gases are assumed to have no interaction between molecules and take up no space (have negligible volume)
