Fucking Gas Laws

Question 1

Ideal Gas Law

Answer 1

PV=nRT

Question 2

P =

Answer 2

P = nRT/V

Question 3

V =

Answer 3

V = nRT/P

Question 4

n =

Answer 4

n = PV/RT

Question 5

T =

Answer 5

T = PV/nR

Question 6

F U Boyle’s Law

Answer 6

P1V1 = P2V2

Question 7

F U too Charle’s Law

Answer 7

V1/T1 = V2/T2

Question 8

And of course F U TOO AvOgadro’s Law

Answer 8

V1/n1 = V2/n2

Question 9

Gas Density at STP

Answer 9

D = molar mass of gas / molar vol.
(in g/L)
Molar vol at STP = 22/4 L/mol

Question 10

Gas Density

Answer 10

D = Pm/RT (in g/L)

(m = molar mass)

Question 11

Partial Pressure

Answer 11

Partial Pressure =
Total Pressure x Mole Fraction

Question 12

R =

Answer 12

R = 0.08206 L atm/ mol K

Question 13

R = (for Urms)

Answer 13

R = 8.314 J/mol K

Question 14

Pressure with Collection of Gas OVER WATER

Answer 14

P (a) = P(total) - P(Water)

Question 15

Root Mean Square Velocity

Answer 15

U(rms) = sqrt(3RT/M)

R = 8.314
M = Molar mass in KG/MOL

Question 16

Rate of Effusion

Answer 16

Rate A / Rate B = sqrt(mB / mA)
Time A / Time B = sqrt(mA / mB)

[m = molar mass]
