Strictly speaking, there is not enough information in just the mole fraction unless you are working in a very dilute solution where you can assume the density of the solution is the same as the density of pure water. If you can do that, then you need to recognise that the mole fraction...
Mole Fraction: The fraction of a solute that is present in a solution expressed in terms of the number of moles of the solute and the solution is called the mole fraction of the solute in the solution. Mathematically it is expressed as {eq}\text{Mole fraction of the solute}...
To calculate the mole fraction of ethyl alcohol (C2H5OH) and water (H2O) in the solution, follow these steps:Step 1: Calculate the moles of ethyl alcohol 1. Given mass of ethyl alcohol: 46 g 2. Molar ma
Mole fraction of water vapor is the ratio of water molecules to air and water molecules. The mole fraction of water vapor is the ratio of the number of mole of water vapor in the moist air - to the total number of mole of dry air and water vapor. The mole fraction of water vapor ...
Mole Fraction:Mole fraction of a component in a solution describes the number of moles of the component present in the total number of moles of all the components present in the solution. x=ni∑niAnswer and Explanation: We are given: Mass of ethan...
