Gas Laws Cheat Sheet
STP is 1 atm and 0C K = 273 + C (Change ALL temp to Kelvin!!!!)
1 atm = 760 mmHg or 760 torr 1000 mL=1 L
1 atm = 101.3 kPa Molar Volume of a Gas at STP 22.4 L/1 mol
V1 = initial volume
Boyle’s Law P1V1 = P2V2 V2 = final volume
P1 = initial pressure
P2 = final pressure
Charles’s Law V1 = V2 T1 = initial temperature (in Kelvin)
T1 T2 T2 = final temperature (in Kelvin)
Gay-Lussac’s Law P1 = P2
T1 T2 Combined Gas Law P1V1 = P2 V2
T1 T2
Ideal Gas Law PV = nRT P = pressure in atm, kPa, or mmHg V = volume in liters
n = number of moles T = temperature in Kelvin
Ideal Gas Constant = R = 0.0821 L • atm = 8.31 L • kPa = 62.4 L • mmHg
mol • K mol • K mol • K
Daltons Law PT = P1 + P2 + P3 + ……. PT = total pressure
P# = the partial pressures of the gases
