Mole fraction represents the number of molecules of a particular component in a mixture divided by the total number of moles in the given mixture. It’s a way of expressing the concentration of a solution.
Therefore, the sum of mole fraction of all the components is always equal to one.. Please note that mole fraction represents a fraction of molecules, and since different molecules have different masses, the mole fraction is different from the mass fraction.

10.6: Gas Mixtures and Partial Pressures [3]
– To determine the contribution of each component gas to the total pressure of a mixture of gases. In our use of the ideal gas law thus far, we have focused entirely on the properties of pure gases with only a single chemical species
The ideal gas law assumes that all gases behave identically and that their behavior is independent of attractive and repulsive forces. If volume and temperature are held constant, the ideal gas equation can be rearranged to show that the pressure of a sample of gas is directly proportional to the number of moles of gas present:
Nothing in the equation depends on the nature of the gas—only the amount.. With this assumption, let’s suppose we have a mixture of two ideal gases that are present in equal amounts

1) Despite being a passage-based question, we should be able to answer this question using external knowledge. To answer this question, we can do a quick overview of chromatography, then we’ll identify the principal factor determining the migration of individual components in the sample
All chromatography works by having a mobile phase (the part that moves), and a stationary phase (the part that stays still) which allow for separation of the different fractions of the original mixture. The higher the adsorption to the stationary phase, the slower the molecule will move through the column
Nonpolar molecules will not be attracted to the water molecules attached to the cellulose and will travel further along the paper, while polar molecules will have a high attraction for the molecules and not travel as far.. Hydrogen bonding to the stationary phase will determine the migration of individual components in the sample
Vapor–liquid equilibrium [7]
In thermodynamics and chemical engineering, the vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the vapor phase and a liquid phase.. The concentration of a vapor in contact with its liquid, especially at equilibrium, is often expressed in terms of vapor pressure, which will be a partial pressure (a part of the total gas pressure) if any other gas(es) are present with the vapor
At vapor–liquid equilibrium, a liquid with individual components in certain concentrations will have an equilibrium vapor in which the concentrations or partial pressures of the vapor components have certain values depending on all of the liquid component concentrations and the temperature. The converse is also true: if a vapor with components at certain concentrations or partial pressures is in vapor–liquid equilibrium with its liquid, then the component concentrations in the liquid will be determined dependent on the vapor concentrations and on the temperature
The VLE concentration data can be determined experimentally or approximated with the help of theories such as Raoult’s law, Dalton’s law, and Henry’s law.. Such vapor–liquid equilibrium information is useful in designing columns for distillation, especially fractional distillation, which is a particular specialty of chemical engineers.[1][2][3] Distillation is a process used to separate or partially separate components in a mixture by boiling (vaporization) followed by condensation
Which of the following statements are correct?1.Mole fraction of a solute $ + $ mole fraction of a solvent $ = 1$2.If equal weights of helium and methane are present in a gaseous mixture, then the mol [8]
1.Mole fraction of a solute $ + $ mole fraction of a solvent $ = 1$. 2.If equal weights of helium and methane are present in a gaseous mixture, then the mole fraction of helium is $dfrac{4}{5}$ .
Hint: mole fraction is the number of molecules of each component present in a mixture divided by total number of moles. Molality is the number of solute in $1kg$ of solvent
1.Mole fraction of a solute $ + $ mole fraction of a solvent $ = 1$. Explanation: mole fraction is defined as the number of molecules of a particular component present in a mixture divided by the total number of moles present in a mixture.
Mole Fraction Calculator [9]
Our mole fraction calculator is a handy tool that computes the mole fraction of your solutions using two different methods. It doesn’t matter if you only know the total number of moles in a solution, or your task requires you to work with solvents and solutes – we’re here for you to help!
Hey! You may also find our molality calculator and molarity calculator useful. Mole fraction is a concentration unit that relates the moles of a particular solute to the total moles of a solution
Our tool can be used in two ways – it all depends on your initial data. – Solute – a minor part of the solution, dissolved in a solvent
