G Molar Mass

You may have noticed that a compound s molar mass is numerically equal to its formula mass. For instance, in Sample Problem F the formula mass of KCIO3 was found to be 122.55 u. Therefore, because molar mass is numerically equal to formula mass, we know that the molar mass of KClOgis 122.55 g/mol. [Pg.227]

Molar Mass Every compound has a characteristic molar mass. Shown here are one mole each of nitrogen (in balloon), water (in graduated cylinder), cadmium sulfide, CdS fellow substance), and sodium chloride, NaCI (white substance). [Pg.227]

Sample Problem G What is the molar mass of barium nitrate, Ba(N03)2 [Pg.227]

One mole of barium nitrate contains exactly one mole of Ba2+ ions and two moles ofNOJ ions. The two moles ofNOJ ions contain two moles of N atoms and six moles of O atoms. Therefore, the molar mass of Ba(N03)2 is calculated as follows. [Pg.227]

Quantitative characteristics of a macromolecule or an assembly of macromolecules, such as mass and mole fractions or percentages as well as the degrees of polymerization and molar masses, may be expressed by placing corresponding figures after the complete name. The order of citation is the same as for the monomer species in the name. Some characteristics cannot be defined for all types of macromolecules and assemblies dealt with in this document, e.g. molar mass of a network. [Pg.391]

Areas of application of radiation degradation of polymers can be usefully classified into (1) modification of polymers, e.g. molar mass or structure, (2) radiation-sensitive polymers, and (3) radiation-resistant polymers. Within the constraints of the required material properties of the polymers, either maximization or minimization of the response to radiation is usually the objective. [Pg.126]

System tunability. The interaction potential typically depends on external conditions (e.g., temperature, ionic strength) and internal system parameters (e.g., molar mass, relative core-to-corona size, degree of crosslinking). It is important to be able to access these parameters easily, in order to obtain maximum flexibility. [Pg.15]
