Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment‚ why they hold the different properties that depict them‚ how their atomic structure may be fathomed‚ and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at
