Question

short note
mole fraction and normality

​

Answer 1

Answer:

The mole fraction is also called the amount fraction. It is identical to the number fraction, which is defined as the number of molecules of a constituent Ni divided by the total number of all molecules Ntot. ... Whereas mole fraction is a ratio of moles to moles, molar concentration is a quotient of moles to volume.

Explanation:

Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. ... Normality is also known as the equivalent concentration of a solution.

Answer 2

Answer:

Short note on Mole fraction —

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 moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, when added together, will equal 1.

Short note on Normality —

Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute's role in the reaction determines the solution's normality. Normality is also known as the equivalent concentration of a solution.
