A pycnometer is a glass flask with a tight fitting glass stopper that is used to obtain the volume of a liquid with high accuracy. A pycnometer has a mass of 25.151 grams when empty, and a mass of 42.481 grams when completely filled with water. The pycnometer has a mass of 47.629 when completely filled with an unknown liquid. What is the density in g/cm³ of the unknown liquid? Assume the density of water is 1.000 g/cm³.
