A special flask used in the determination of densities, called a pycnometer, has a mass of 16.3179 g when empty, and it has a mass of 48.0250 g when filled with water at 20.0°C. When this same pycnometer is filled with ethyl alcohol at 20.0°C, it is found to have a mass of 41.3934 g. Find the density of ethyl alcohol at 20.0°C. (Given: at 20.0°C, the density of water is 0.9982 g/mL)
