Refractive index of a 1M sorbitol solution

[O2F]

I would like to find the refractive index of a 1M sorbitol solution.

Is there any resource out there that lists refractive indexes? Is there any way to calculate this?

Thank you

You can look up standard properties for specific substances.

There will also be references in your college library.
But you should always measure (where you can) the properties of any solution you actually make in the lab instead of relying on some book value.
