Expert Answer:

Ideal Gas law 
PV = nRT 
n = number of moles 
R = universal gas constant = 8.3145 J/mol K 
 
 
Boyle's law 
P1V1 = P2V2 
 
 
Gay-Lussac law 
P1   =   P2
T1 T2

 
 
Combined Gas law 
P1V1   =   P2V2
T1 T2

 
 
 
 
 
 
Charles law 
V1   =   V2
T1 T2

 
 
 
 
Concentration is the ratio of solute and solvent. 
Concentration can be measured using molarity, molality and mole fraction. 

Molarity (M) =   moles of solute
liters of solution



Molality (m) =   moles of solute
kg of solution
 
 
 
Mole-fraction (Xa)= molesa
molesa + molesb ....
 
 
 
 
 
 
 
One mole of gas has volume of 22.4 liter at STP.
