Mass spectrum (electron ionization) UV/Visible spectrum; Gas Chromatography; Data at other public NIST sites: ... , The enthalpies of combustion and formation of p-tertiary butyl phenol and naphthalene, Egypt. It is a white solid. Naphthalene, a hydrocarbon, has an approximate molar mass of 128 g/mole. It is an isomer of 2-naphthol differing by the location of the hydroxyl group on the naphthalene ring. Based on the graph plotted for the pure solvent (naphthalene), the freezing point obtained is 76.0 o C. About Naphthalene; Naphthalene weighs 1.162 gram per cubic centimeter or 1 162 kilogram per cubic meter, i.e. The freezing-point depression constant for camphor is 37.7 (C*kg/mol.) density of naphthalene is equal to 1 162 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.In Imperial or US customary measurement system, the density is equal to 72.54 pound per cubic foot [lb/ft³], or 0.6717 ounce per cubic inch [oz/inch³] . J. Aim: To determine the molar mass of unknown by determining the freezing point depression of a naphthalene … The experimental data shown in these pages are freely available and have been published already in the DDB Explorer Edition.The data represent a small sub list of all available data in the Dortmund Data Bank.For more data or any further information please search the DDB or contact DDBST..
