A glass flask whose volume is 1000 cm at a temperature of 0.500 C is completely filled with mercury at the same temperature. When the flask and mercury are warmed together to a temperature of 52.0 C, a volume of 8.50 cm of mercury overflows the flask. If the coefficient of volume expansion of mercury is Hg = 1.80x10-4/K, compute glass, the coefficient of volume expansion of the glass. Express your answer in inverse kelvins.
