Answer of this question is as we know r m equals to n r square minus 1 divided by n r square plus 2 to v m.
00:18
So, here r m is the molar refraction, n r is the refractive index, v m is the molar volume.
00:26
So, the above equation can be arranged like this n r equals to v m plus 2 r m divide by v m plus sorry v m minus r m and raise to the power 1 by 2.
00:46
So, here v m equals to m by density.
00:57
So, this is equals to 10 .02 gram per mole divide by 1 .00 gram per centimetre cube.
01:07
So, this is equals to after calculation 10 .02 centimetre cube by mole.
01:15
Now, we know r m equals to 4 pi alpha n a divide by 3.
01:28
So, here alpha dash is the optical frequency...
