5

molar concentration

Mi Vi = Mf Vf

6

Pressure

P = force / area

7

Boyle's Law

Pi Vi = Pf Vf, constants n, T

8

Charles's law

Vi / Ti = Vf / Tf, constants n, P

9

Avagardro's law

Vi / ni =Vf / nf, constants T, P

10

Ideal gas equation

PV = nRT

11

density of a gas

d= PM / RT, Pressure*Molar Mass / R*Temperature
