exam #4

Kw or constant for water

1x10¹⁴M²
Sea level = 1 atm =?
- STP
- 760 torr =
- 760 mmHg =
- 101.325 Kpa =
- 14.696 psi
Kelvin to Celcius
- 0 C = 273 K
- 0K = -273.15 C
room temp =

25 C = 298 K
Charles Law
volume - temp

V₁T₂ = V₂T₁
Boyles Law
pressure - volume

P₁V₁ = P₂V₂
Combined Gas Law

P₁V₁T₂ = P₂V₂T₁
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
R, Gas constant =

0.0821
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
also M=DRT / P
Grahams Law
- rate of gas a / rate of gas b =
- √(molar mass b / molar mass a)
avagadros number

6.02x10²³
moles to liters

1 mole = 22.4 L
