Volumetric flask made of Pyrex is calibrated at 20.0°C. It is filled to the 155-mL mark with 34.5°C Mercury. After the flask is filled, the Mercury cools and the flask warms so that the combination of Mercury and flask reaches a uniform temperature of 32.0°C. The combination is then cooled back to 20.0°C. (The average volume expansion coefficient of Mercury is 1.82 10-4(°C)−1.) (a) What is the volume of the Mercury when it cools to 20.0°C?
