Question

define mole fraction​

Answer 1

Explanation:

Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of molesof a solution. Because it is a ratio,mole fraction is a unitless expression.

Answer 2

Answer:-

Mole fraction is denoted by X

Defination:-

One of the unit of Concentration is mole fraction,and mole fraction is equal to the number of moles of a component divided by the total number of moles of a solution.

Mole fraction of solute

a) Mole fraction of solute is define by number of moles of solute divided by the total numbers of moles of solution.

=> X (solute)

=(moles of solute)/(total moles of solution)

Mole fraction of solvent

b) Mole fraction of solvent is defined by number of moles of solvent divided by the total numbers of moles of solution.

=> X (solvent)

=(moles of solvent)/(total moles of solution)
