What is the molar mass of chlorine gas?

Answer: The correct molar mass of chlorine gas (Cl2) is:

70. 90 g/mol

Chlorine is a halogen which in its gaseous state forms a diatomic molecule, and this means that a molecule of chlorine will contain two chlorine atoms. To calculate the molar mass of Cl2 we are required to determine the atomic mass of chlorine and then multiply it by two. The atomic mass of chlorine is roughly around 35. its atomic weight is 45 g/mol if we average the two stable isotopes, isotopic mass. Thus, the molar mass of Cl2 id 2 * 35 = 70. 90 g/mol. This value is the mass of one mole of chlorine gas molecules that exists in the air or the gaseous state. Molar mass is a significant concept in chemistry since it is used in the calculation of ratios, density of gasses, and conversion between a mass and the number of molecules of a sample. In quantitative chemistry and chemical engineering, this has become a fundamental concept.
