\nThe average atomic mass of chlorine atom is approximately 35.5 u.
\n<\/section>\n
\nChlorine occurs naturally as a mixture of two main isotopes: chlorine-35 (\u00b3\u2075Cl) and chlorine-37 (\u00b3\u2077Cl). Their approximate natural abundances are about 75% for \u00b3\u2075Cl (mass \u2248 34.97 u) and 25% for \u00b3\u2077Cl (mass \u2248 36.97 u). The average atomic mass is a weighted average of the masses of its isotopes based on their natural abundance.
\n<\/section>\n
\nAverage atomic mass = (0.75 \u00d7 34.97 u) + (0.25 \u00d7 36.97 u) \u2248 26.23 u + 9.24 u \u2248 35.47 u, which is rounded to 35.5 u.
