![]() InChI (IUPAC International Chemical Identifier) information of Oxygen.The molecular formula of Oxygen is given in chemical formula page of Oxygen, which identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. The molecular structure image of Oxygen is available in chemical structure page of Oxygen, which provides the molecular geometry information, i.e., the spatial arrangement of atoms in Oxygen and the chemical bonds that hold the atoms together. ![]() The Oxygen structure data file can be imported to most of the chemistry-related software, providing three-dimensional visualization and further analysis. The structure data file (SDF/MOL File) of Oxygen is available for download in the SDF page of Oxygen, which provides the information on atoms, bonds, connectivity and coordinates of Oxygen. Structure Data File (SDF/MOL File) of Oxygen.quantum Chemical Computation Data (20 sets)Īdditional Information for Identifying Oxygen Molecule.Molecular Orbital (HOMO & LUMO) Visualization.Normal Mode Frequency Analysis with Animation.Activity Score for Nuclear Receptor Ligands.Activity Score for Ion Channel Modulators.Moriguchi Octanol-Water Partition Coefficient (logP).Ghose-Crippen Octanol-Water Partition Coefficient (logP).LogP (Octanol-Water Partition Coefficient).Heat of Vaporization at Normal Boiling Point.Upper Flammability Limit Volume Percent.Lower Flammability Limit Volume Percent.Standard State Gibbs Energy of Formation.The atomic mass takes into account the isotopic distribution of the element in a given sample.įor physicochemical, thermodynamic, transport, spectra, and other property data & information, the followings are available from “Mol-Instincts”, a chemical database based on quantum chemical computations: Molecular masses are calculated from the standard atomic weights of each nuclide, while molar masses are calculated from the atomic mass of each element. Molecular weight is actually an older term of “relative molar mass” or “molecular mass”, which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol. The exact term of the above molecular weight is “molar mass”, which is based on the atomic mass of each element. ![]() The molecular weight of Oxygen is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be: (i) Your answer for part (h) should be three times as large as the answer for part (g).The Oxygen molecule consists of 2 Oxygen atom(s) - a total of 2 atom(s). ![]() What is the average force the molecule exerts on one of the walls of the container? (Assume that the molecule’s velocity is perpendicular to the two sides that it strikes.) (f) What is the average force per unit area? (g) How many oxygen molecules traveling at this speed are necessary to produce an average pressure of 1 atm? (h) Compute the number of oxygen molecules that are contained in a vessel of this size at 300 K and atmospheric pressure. What is (a) the average translational kinetic energy of an oxygen molecule at a temperature of 300 K (b) the average value of the square of its speed (c) the root-mean-square speed (d) the momentum of an oxygen molecule traveling at this speed? (e) Suppose an oxygen molecule traveling at this speed bounces back and forth between opposite sides of a cubical vessel 0.10 m on a side. Oxygen ( O 2 O_ O 2 ) has a molar mass of 32.0 g/mol.
