To calculate the average atomic mass of chlorine:

Given the fractional natural abundance of _{}^{35}\textrm{Cl} with 34.9689\ u molar mass is 75.77\% and that of  _{}^{37}\textrm{Cl} with 36.9659\ u molar mass is 24.23\%.

Therefore we have,

Average Atomic mass of Chlorine:

= \left ( 0.7577\times34.9689\ u \right ) + \left ( 0.2423\times36.9659\ u \right )

= 26.4959\ u + 8.9568\ u = 35.4527\ u
