Molecular Mass Of Cl2
The Composition of Chlorine Gas
Chlorine gas (Cl2) consists of two chlorine (Cl) atoms bonded together. Chlorine gas is a gas that appears pale greenish-yellow and has a distinctive, pungent odor. It is widely employed across various industries, including water treatment, disinfection, and chemical synthesis, among others.
Calculating the Molecular Mass
To calculate the mole mass of Cl2, we need to consider the atomic masses of chlorine (Cl). The atomic mass of chlorine (Cl) is approximately 35.453 atomic mass units (amu).
The molar mass, also known as molar weight, of Cl2 is determined by summing the atomic masses of its constituent elements.
Molecular Mass of Cl2 = 2 × Atomic Mass of Cl Molecular Mass of Cl2 = 2 × 35.453 amu Molecular Mass of Cl2 ≈ 70.906 amu
Therefore, the molar mass of chlorine gas (Cl2) is approximately 70.906 atomic mass units (amu) or 70.906 grams per mole (g/mol).
