Question

What is meant by molar refraction ?​

Answer 1

Answer:

Hey mate

Mole fraction is the fraction of number of Mole upon total numbers of moles of the solution.

Explanation:

Mole fraction is a unit of concentration which is unit less because it is a fraction.

Answer 2

Answer:

from wikipedia ,the free encyclopedia ,molar refractivity is a measure of the total polarizability of a mole of a substance and is dependent on the temperature, the index of refraction and the pressure .the molar refractivitity is defined as where is the avogadro constant and is the mean polarizability of a molecule.
