Raoult's law
the vapor pressure of an ideal solution is dependent on the vapor pressure of each chemical
component and the mole fraction of the component present in the solution.[2]
Once the components in the solution have reached equilibrium, the total vapor pressure p of the
solution is:
and the individual vapor pressure for each component is
where
pi is the partial pressure of the component i in the mixture (in the solution)
p*i is the vapor pressure of the pure component i
xi is the mole fraction of the component i in the mixture (in the solution)
Ideal Gas Law Calculation
The Ideal Gas Law(General Gas Equation) is the equation of state of a hypothetical ideal gas.
Calculate the pressure, volume, temperature and moles of gas.
Ideal Gas Law:
Gas Equation: PV = nRT
where,
P = pressure,
V = volume,
n = moles of gas,
T = temperature,
R = 8.314 J K-1 mol-1, ideal gas constant.
Boyle's/Mariotte's Law Calculation
Boyle's law states that the volume of a gas increases when the pressure decreases at a constant
temperature.
Boyle's/Mariotte's Law:
Gas Equation: PiVi = PfVf
where,
Pi = Initial Pressure,
Vi = Initial Volume,
Pf = Final Pressure,
Vf = Final Volume.
Charles' Law Calculation
Charles' Law states that the volume of a given amount of gas is directly proportional to the
temperature provided the amount of gas and the pressure remain fixed.
Charles' Law:
Gas Equation: Vi/Ti = Vf/Tf or Vf/Vi = Tf/Ti or ViTf = VfTi
where,
Vi = Initial Volume,
Ti = Initial Temperature,
Vf = Final Volume. Tf = Final Temperature,
Dalton's Law Calculator
The Pressure of the mixture gas is equal to the sum of the pressure of the partial gases in a
container'' is the statement of Dalton's partial pressures law. Calculate the pressure of combined
gases with known values of temperature and mole of gas.
Formula:
Ptot=p1+p2+p3+...+pm
(or)
ptot={n1+n2+n3+...nm}RT/v
Where,
p1,p2,p3, ...,pm= Partial pressures of the individual gases in the mixture.
V = volume,
T = temperature,
n1,n2,n3, ...,nm=n is the total amount of gas of the m gases present in the mixture,
R = 8.314 J K-1 mol-1, ideal gas constant. The Dalton's law calculator is derived from the law of
partial pressures.
Gay-Lussac's Law Calculation
Gay-Lussac's Law states that the pressure of a fixed amount of gas at fixed volume is directly
proportional to its temperature in kelvins.
Gay-Lussac's Law:
Gas Equation: Pi/Ti = Pf/Tf or PiTf = PfTi
where,
Pi = Initial Pressure,
Ti = Initial Temperature,
Pf = Final Pressure,
Tf = Final Temperature.
