Which option gives the correct relation for the mole fraction of a component?
Answer and explanation
Correct answer: Moles of a component divided by total moles
The mole fraction of component i is defined as Xi = ni/ntotal, where ni is the number of moles of that component and ntotal is the sum of the moles of every component in the solution. It is a dimensionless quantity, and the mole fractions of all components add up to one. Option D describes molarity, not mole fraction.
