What is Density?

A pycnometer is a device for measuring the density of liquids. It is a glass flask with a close-fitting ground glass stopper having a capillary hole through it. (a) The volume of the pycnometer is determined by using distilled water at 20^∘C with a known density of 0.99820  g / mL. First, the water is filled to the rim. With the stopper in place, the fine hole allows the excess liquid to escape. The pycnometer is then carefully dried with filter paper. Given that the masses of the empty pycnomet

A pycnometer is a glass apparatus used for accuratelydetermining the density of a liquid. When dry and empty, a certainpycnometer had a mass of 27.364 g. When filled with distilled waterat 25.0°C, it weighed 36.448 g. When filled with chloroform (aliquid once used as an anesthetic before its toxic properties wereknown), the apparatus weighed 40.821 g. At 25.0°C, the density ofwater is 0.99704 g/mLWhat is the density of chloroform?
