Document Summary
Basic chemistry ii: a substance consisting of two or more different atoms, in specific proportions, bonded together in a specific pattern, molecules, the smallest unit of a compound that retains all of the properties of that compound. Isomers: molecules with the same molecular formula, but a different arrangement of atoms. Three types of isomers: structural isomers, geometric isomers, and enantiomers. The sum of the atomic masses for all of the atoms in a molecule. Carbon atomic #: 6 atomic mass: 12: hydrogen atomic #: 1 atomic mass: 1, oxygen atomic #: 8 atomic mass: 16, multiple atomic mass x subscript and then add together= 342. The mass of a substance equal to its molecular weight in grams. Contains a constant number of molecules: avogadro"s number of molecules, 6. 022 x 1023. 1 mole = the mass of a substance equal to its gram molecular weight.
