By silver salt method - Silver salt method is used for determining the molecular masses of carboxylic acids. This method is based on the fact that they form insoluble silver salts, which upon heating decompose to leave a residue of metallic silve..

Determination of the Molecular Formula of a Compound - The empirical formula of the compound is written. The empirical formula mass is calculated by adding the atomic masses of all atoms present in the empirical formula. The molecular mass..

Example: 21 - An organic compound has the following percentage composition: C= 40%, H = 6.66%, O = 53.33%. Find its molecular formula (Relative atomic mass of C=12, H=1, O=16 and Relative molecular mass of the compound = 18..

The molecular mass of a substance is the relative mass of its molecule as compared with the mass of a 12 C atom taken as 12-units. It indicates the number of times; one molecule of the substance is heavier than at..

A known mass W B of the non-volatile solute is dissolved in a known mass (W A ) of the volatile solvent to prepare a dilute solution and relative lowering of vapor pressure is determined experimentally. Knowing the molecular mass (M A ) of the sol..

Molecular Mass of Polymers - Generally a polymer sample contains chains of varying lengths and therefore its molecular mass is always expressed as an average. In contrast, natural polymers such as proteins, contains chains of identical length and hence have d..

Gram molecular mass of a substance is the relative molecular mass of the substance, expressed in gram..
