The mole fraction of a solute is the ratio of the number of moles of that solute to the total number of moles of solute and solvent in solution. Because it's a ratio of moles to moles, the mole fraction is a dimensionless number, and of course, it's always less than one. Molar ...
Mole fraction refers to a unit of concentration. It is a formula in the field of physics that is unitless expression. Mole fraction is equal to the number of a component’s moles divided by the total number of a solution’s moles. Also, when analyzing the solutions chemist us...

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...
But when I am trying to run through simulink it gives errors. I have attached the error picture. I have used coder.extrinsic command while using cantera functions. I have tried to search for the same. One of the solution I found was to write S function but...
