Gas Formulas

Question 1

Boyles Law

Answer 1

(P1)(V1)=(P2)(V2)

Question 2

Charles Law

Answer 2

V1/T1=V2T2

Question 3

Combined Gas Law

Answer 3

(P1)(V1)/(P2)(V2)=(T1)/(T2)

Question 4

Gas Density

Answer 4

Molar mass/ molar volume {22.4L}

Question 5

PV=nRT

Answer 5

(Pressure)(volume)=(# of mols)(.082 L atm/ mol K)(temperature)

Question 6

Root mean square velocity

Answer 6

Square root of 3RT/M where r =8.314 and M= molar mass in kg/mole

Question 7

Kinetic energy

Answer 7

KE=3/2nRT

R=8.314
