(a) molecular mass and molar mass;. Molecular mass refers to the sum of the atomic masses of all the atoms in a molecule, while molar mass refers to the mass of one mole of a substance . Molecular mass is expressed in atomic mass units (amu) or grams per mole (g/mol), while molar mass is expressed only in g/mol
(b) empirical and molecular formulas;(b) The composition of a chemical compound can be described using either a molecular formula or an empirical formula. The molecular formula provides the precise number of atoms of each element in a compound's molecule, whereas the empirical formula provides the compound's simplest whole number ratio of atoms.
(c) Chemical substances can be given systematic names or absurd names. The structure of the chemical is precisely and unambiguously described by systematic nomenclature, which are based on a set of principles established by the International Union of Pure and Applied Chemistry (IUPAC). Trivial names, on the other hand, are based on historical, regional, or general usage and might vary greatly depending on the language or place.
(d) Hydroxyl and carboxyl functional groups are two types of functional groups commonly found in organic molecules. Hydroxyl groups (-OH) consist of an oxygen atom and a hydrogen atom bonded to a carbon atom and are found in alcohols and carbohydrates. Carboxyl groups (-COOH) consist of a carbon atom, an oxygen atom, and a hydroxyl group bonded to the same carbon atom and are found in carboxylic acids.
