Explanation:
Formula to calculate refractive index of n is as follows.
n =
where, = mole fraction of A
= mole fraction of B
= refractive index of A
= refractive index of B
Hence, putting the given values into the above formula as follows.
n =
1.5248 = ........ (1)
Also, it is known that = 1
and, ......... (2)
Now, put equation (2) in equation (1) as follows.
1.5248 =
1.5248 =
= 0.467
And, the value of is calculated as follows.
=
= 0.533
Hence, mole percentage of A will be calculated as follows.
Mole % of A =
=
= 46.7%
Thus, we can conclude that the mole percent of A in their mixture is 46.7%.
