Molecular Weight of Substances Definition and molecular weight (molar mass) of some common substances. The molecular weight of a substance, also called the molar mass , M, is the mass of 1 mole of that substance, given in M gram. In the SI system the unit of M is (kg/kmol) and in...
Method for determining the molecular weight of a substance contained in a solutionTouradj SoloukiAlireza Fattahi
In many chemical laboratories, it is necessary to determine the molecular weight of a substance. For example, suppose a new compound has been synthesized. A laboratory can have a “CHO analysis” done commercially, by a combustion experiment. (Most labs are not set up to do this ...
Thus, this law relates the molecular weight of a substance with its vapor density Answer and Explanation:1 Avogadro's law compares the vapor density of a gas to its molecular weight. According to this law: Vapor density of a gas = (mass of the ...

Themolecular massof a substance is the mass of one molecule of that substance, in unified atomic mass units (Drews, 1998; Speight, 2015). This is distinct from therelative molecular massof a molecule, frequently referred to by the termmolecular weight, which is the ratio of the mass of th...
From the molarity formula, the calculation of the weight of any substance is also possible. The moles are further having a formula as given weight by molar mass. The two formulas for molarity can be used based on the given values.
