Aspecial 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)
