How do you find ideal gas constant?

Answer 1

- Boyle Law: @ constant T, there is an asymptotic relationship between V & P

o In other words, V is inversely proportional to Pwhen T is held constant.

o PV=E(constant)

- Charles and Gay-Lussac's Law: There is a linearly proportional relationship between temperature and volume, at a constant number of moles and pressure.

o If the pressure is held constant, the volume V is equal to a constant times the temperature T

o V=BT (absolute T -> t=T-273.15)

So, Boyles Law: P0V0=P1V1 (at constant T)

Charles Law: V0/T0=V1/T1

Combined Gas law:

- The combined gas law is a gas law, which combines Charles's law, Boyle's law, and Gay-Lussac's law.

o P0[(T1/T0)V1]=P1V1

o P0V0/T0=P1V1/T1

Avagadro's Law: "Equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties."

- As an example, equal volumes of molecular hydrogen and nitrogen contain the same number of molecules when they are at the same temperature and pressure, and observe ideal gas behavior.

- V/n=Kconstant

- Measurement: @ constant T0 & P0

V = 22.44[liters/mole]

Taking all that into consideration, we just plug and chug -

P1V1/T1=R=(1atm)(22.44l/mole)/(273.15K)=.08205

.08205(liter*atm/mol*k) x 101,325 ((molecules/m^2)/atm) = 8.3144(N*m/mol*K) = 8.3144(J/mol*K) = R

Answer 2

can anybody, prove the gas constant 8.314 is universal value?

thanks

Answer 3

The gas constant value; as represented by the symbol R; is a physical constant and is important for many equations like Nernst. The equation is as follows: R = 8.3144621(75) J/mol K.

Answer 4

The ideal gas constant, denoted by R, can be found by multiplying Avogadro's number (6.022 x 10^23) by Boltzmann's constant (1.38 x 10^-23 J/K). This gives a value of approximately 8.31 J/(mol*K).
