Molecular Mass: An Overview
The mole mass, also known as molar mass, is a fundamental concept in chemistry. It represents the mass of one mole of a particular substance and is typically expressed in atomic mass units (amu) or grams per mole (g/mol). A mole is a unit used to quantify the amount of a substance and contains approximately 6.022 x 10^23 entities, known as Avogadro’s number. Molecular mass is numerically equivalent to the atomic or mole weight of the substance.
The Molecular Mass of Chlorine (Cl)
Chlorine exists naturally as two stable isotopes: chlorine-35 (^35Cl) and chlorine-37 (^37Cl). The atomic masses of these isotopes are as follows:
- The atomic mass of chlorine-35 is approximately 34.97 amu.
- The atomic mass of chlorine-37 is approximately 36.97 amu.
To calculate the mole mass of chlorine (Cl), we consider the weighted average of the isotopic masses, taking into account their natural abundance. In the case of chlorine, approximately 75.77% is chlorine-35, and about 24.23% is chlorine-37.
mole Mass of Chlorine (Cl) = (0.7577 * Atomic Mass of ^35Cl) + (0.2423 * Atomic Mass of ^37Cl)
mole Mass of Chlorine (Cl) ≈ (0.7577 * 34.97 amu) + (0.2423 * 36.97 amu)
