  1. Kw or constant for water
    1x1014M2
  2. Sea level = 1 atm =?
    • STP
    • 760 torr =
    • 760 mmHg =
    • 101.325 Kpa =
    • 14.696 psi
  3. Kelvin to Celcius
    • 0 C = 273 K
    • 0K = -273.15 C
  4. room temp =
    25 C = 298 K
  5. Charles Law
    volume - temp
    V1T2 = V2T1
  6. Boyles Law
    pressure - volume
    P1V1 = P2V2
  7. Combined Gas Law
    P1V1T2 = P2V2T1
  8. Ideal gas law
    • PV = nRT
    • P= pressure atm
    • V= volume liters
    • n= #moles
    • R= gas constant = 0.0821(L.atm/mol.K)
    • T= temp Kelvin
  9. R, Gas constant =
    0.0821
  10. Molecular weight and density equation
    • D=(MP)/(RT)
    • note : D=m/v
    • M= molar mass g/mol
    • D= density = mass/volume
    • R= gas constant = 0.0821
    • T= temp K
    • P= pressure atm
  11. also M=DRT / P
  12. Grahams Law
    • rate of gas a / rate of gas b =
    • √(molar mass b / molar mass a)
  13. avagadros number
    6.02x1023
  14. moles to liters
    1 mole = 22.4 L
