Fill the slab with a test liquid and have fun :)
The best way to measure index of refraction in your case is by method of interferometry. Refer to slide 12 of the PPT at the site below.
n1 x sin(theta1) = n2 x sin(theta2)
n1 - refraction index of media 1
theta 1 - angle of refraction in media 1
To begin using Snell's Law (mentioned above ) you may need to know dimensions of the glass slab and you have not one but actually five mediums; air, glass, liquid, glass, air. Each time the light passes across the new medium it will bend.
Have fun.

Fill the slabs with the liquids one at a time.
Put the slab on a piece of white paper and shine a narrow beam of light through it. On the paper, trace the outline of the glass slab and trace the incoming beam and the path of the beam through the liquid.
Now, get a protractor and put a perpendicular to the face of the glass at the point where the beam enters the glass.
Measure the angle from the incoming beam to the perpendicular line. Measure the angle of the beam in the liquid from the perpendicular.
These angles are Theta1 and Theta2.
Use the formula Sin(T1)/Sin(T2) = Index2/Index1. Where Index1 is the index of refraction of air which is 1. So,
Index2 = Sin(T1)/Sin(T2) as long as the medium you are coming from is air.

No, yet i did attempt and a brilliant style of instances to devour soup with a spoon, fairly if a soup is thick (you may thicken the soup efficiently via including some flour). It takes extra time, so I take excitement in it longer
