Question

abay yaar koi toh kar do answer but faltu nhi

Light passes successively through 2 polarimeters tubes each of length 0.29m. The first tube contains dextro rotatory solution of concentration 60 kg m^-3 and specific rotation 0.01 rad m²kg^-1. The second tube contain laevorotatory solution of concentration 30 kgm^-3 and specific rotation 0.02 rad m² kg^-1. what is the net rotation produced.? ​

Answer 1

Explanation:

[α] = α(observed)/ (c×l)

here, c is concentration

l is length of tube in dm

And, this holds for standard condition

In first case, l = 0.29 m = 2.9 dm

c = 60 kg/m³

and, specific rotation [α] is 0.001

-------------------

Abb bas value put karlo, and take one raotation as +ve and another one -ve

Then add them, you get net rotation.

i think itna maths aata hoga :p

Good luck
