Volume of glycerin = Volume of Vessel  *  volume  coefficient of expansion of glass /  volume  coefficient of expansion of glycerin

Explanation:

Volume of glass =  V  = 250 cc

Volume of glycerin = v   cc

V - v  = space unoccupied

α = volume  coefficient of expansion of glass

β = volume  coefficient of expansion of glycerin

ΔT = Change in temperature

Vₙ = V( 1 + αΔT)

vₙ = v( 1 + βΔT)

Vₙ - vₙ =  space unoccupied  

space unoccupied    remains constant

Vₙ - vₙ = V - v

=>  V( 1 + αΔT) - v( 1 + βΔT) = V - v

=> V + VαΔT - v - vβΔT = V - v

=> vβΔT = VαΔT

=> vβ  = Vα

=> v = Vα/β

=> v = 250α/β

Volume of glycerin = Volume of Vessel  *  volume  coefficient of expansion of glass /  volume  coefficient of expansion of glycerin

if Values are given then substitute .

Assuming :

volume  coefficient of expansion of glycerin = 0.000597  per °C

volume expansion of glass =3×0.000009=0.000027  per  °C

v = 250α/β = 250  * 0.000027 / 0.000597

=> v = 11.3 cc
