force/area
2
Q
units for pressure
A
- 1.000 atmosphere (atm)
- 760.0 millimeter of mercury (mmHg)
- 760.0 torr
- 101,325 Pascal (Pa)
- 101.325 kPa
3
Q
Boyle’s Law (pressure and volume)
A
P1V1 = P2V2
4
Q
Charles’s Law (volume and temperature)
A
V1/T1 = V2/T2
temp must be in kelvin
Needs same units of V1 and V2 to cancel
5
Q
Gay Lussac’s Law (pressure and temperature)
A
P1/T1 = P2/T2
temp must be in kelvin
6
Q
Avogadro’s Law ( volume and no. of moles)
A
V1/n1 = V2/n2
7
Q
Combined gas law
A
P1V1/n1T1 = P2V2/n2T2
8
Q

Pressure - atm
Volume - L
R - 0.0821 Latm/Kmol
T - K
10
Q
Gas stoichiometry if not STP
A
use ideal gas law
