A flask is filled with 1.53 L (L = liter) of a liquid at 92.2 °C. When the liquid is cooled to 15.1 °C, its volume is only 1.36 L, however. Neglect the contraction of the flask. What is the coefficient of volume expansion of the liquid?

V*a*(T2-T1) = 136.
1.53*a*(15.1-92.2) = 136, a = ?.
Convert liters to cm^3
1 liter = 1000 cm^3

ΔV= βV(initial)ΔT
1530 - 1360 = β (1530)(92.2 -15.1)
170/118116 = 118116β/ 118116
β= 144.11*10^-3 (C degrees)^-1
