Define the following terms:
Mole fraction

Solution

Answer:
mole fraction can be defined as :

Mole fraction of a component =

$\frac{Number of moles of the component}{Total number of moles of all the components}$

for example
Mole fraction. The ratio of the moles of a component A to the total moles of the solution is called the mole fraction of A. It is denoted by symbol x. For a binary solution of components A and B Mole fraction of A = x_{A
$= \frac{Moles of A}{Total moles of solution} = \frac{n_{A}}{n_{A} + n_{B}}$}Mole fraction of B = x_{B
$= \frac{Moles of B}{Total moles of solution} = \frac{n_{B}}{n_{A} + n_{B}}$}
