Question

What is the sum of mole fraction of all componenets in a three component system?

Answer 1

Answer⭐⭐⭐

For each component (i) in a multi
component system, the mole fraction
x(i) is the number of moles n(i) of that component divided by the total number

of moles n in the system.
So for a three component system,
you add the number of moles of each
component to get the total number of
moles. Then, to get the mole fraction
of any component divide its number of

moles by the total.

If you have a solution containing 3

solutes for which you know the molarity,

just add the molarities and get the mole

fraction of any solute as above.

The mole fraction will generally be a

decimal fraction

Answer 2

Explanation:

Sum of the mole fractions of all the components is unity. x1 + x2 + x3 = 1
