The molar mass of chlorine (Cl) is approximately 35.45 grams per mole. This value is derived from the average atomic mass of chlorine, which takes into account the different isotopes of chlorine and their relative abundances. Chlorine has two stable isotopes: chlorine-35 and chlorine-37. The atomic mass of chlorine-35 is about 34.97, and the atomic mass of chlorine-37 is about 36.97. The molar mass is calculated by averaging these masses based on their natural occurrence, resulting in the value of 35.45 grams per mole.
