A pycnometer is a glass flask with a tight fitting glass stopper that can be used to determine the density of an insoluble solid by measuring the volume of water ejected out of the pycnometer when sample of the solid is placed in it. Determine the density in g/cm³ of an unknown metal alloy sample from the following measurements. Assume the density of water is 1.000 g/cm³. Mass of clean pycnometer = 25.151 g Mass of clean pycnometer plus water = 42.481 g Mass of clean pycnometer plus metal sample = 39.105 g Mass of clean pycnometer plus metal plus water = 54.265 g (after ejected water is dried from the outside surface)

Introduction to chemistry

Chemistry is a branch of science that deals with the analysis of material and the substances that comprise it. It also manages the properties of these substances and their reactions to form new substances. It is basically centered on particles and atoms that make up components and mixtures. These chemical species will in general connect using bonds.
