Raoult's law
the vapor the vapor pressure of an ideal an ideal solution is dependent on the vapor pressure of each chemical each chemical component and the mole the mole fraction of the component present in the solution.[2] solution.[2] Once the components in the solution have reached equilibrium, reached equilibrium, the the total vapor pressure p of the solution is:
and the individual vapor pressure for each component is
where pi is the partial the partial pressure of the component i in the mixture (in the solution) p*i is the vapor the vapor pressure of the pure component i xi is the mole 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 h ypothetical 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, -1 -1 R = 8.314 J K mol , 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 = Pf Vf 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 = Vf Ti 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 mol , ideal gas constant. The Dalton's law calculator is d erived 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 = Pf Ti where, Pi = Initial Pressure, Ti = Initial Temperature, Pf = Final Pressure, Tf = Final Temperature.
