A glass flask whose volume is 1000 cm3 at a temperature of 0.900 °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 8.15 cm3 of mercury overflows the flask.
If the coefficient of volume expansion of mercury is βHg = 1.80×10-4 /K , compute βglass, the coefficient of volume expansion of the glass.
Express your answer in inverse kelvins.
