Let x be the mass of solution.

Mass of NaOH= 100x×20

Molar mass of NaOH=40g

∴ Number of moles= ( 10020x)/40= 200x

Now mass of solvent in the solution= x−

100

20x

= 100

80x

∴ Molality=

(80x/100)x/200×1000=6.25M

Define Snell's law of refraction. A ray of light is incident on a glass slab at an angle of incidence of 60°. If the angle of refraction be 32.7°, calculate the refractive index of glass. (Given: sin 60° = 0.866 and sin 30° = 0.5).
