Gas Law Equations & Conversions

Question 1

Pressure = Force/Area

Answer 1

measuring pressure

Question 2

760 mmHg
760 torr
(14.7 lb/in^2)

Answer 2

= 1 atm

at Sea Level and 0 degrees celsius

Question 3

An ideal gas exhibits linear relationships between temperature, volume, pressure and amount
(*No ideal gas actually exists but most simple gases behave almost ideally at ordinary temperature and pressure)

Answer 3

describes physical behavior of gases

Pv = nRT

Question 4

[P(1)V(1) = P(2)V(2)]
At constant temperature, the volume occupied by a fixed amount of gas is inversely proportional to the external pressure (V corresponds to 1/P or PV = constant)

Answer 4

Boyle's Law:
At fixed T and n, 
P decreases as V increases
P increases as V decreases
*Absolute zero (0K) is the temperature at which an ideal gas would have zero volume

Question 5

[V(1)/T(1) = V(2)/T(2)]
At constant pressure, the volume occupied by a fixed amount of gas is directly proportional to its absolute (Kelvin) temperature (V corresponds to T or V/T = constant)

Answer 5

Charle’s Law:
At fixed P and n,
T decreases as V increases
T increases as V decreases

Question 6

STP =
1 atm / 760 torr / 760 mmHg
0*C / 273.15 K

Answer 6

Gas behavior at Standard conditions

Question 7

22.14 or 22.414 L

Answer 7

Standard molar volume-

volume of 1 mole of an ideal gas at STP

Question 8

m/M = m/M

mass/molar mass) = (mass/molar mass

Answer 8

moles (g) = moles (g)
*of an ideal gas
(mass/molar mass = n, # moles)
