35.5

$\huge \sf \color{blue}\underline{\underline{Solution }}:$

$\large \sf \color{red}{To \ calculate \: :}$

Average atomic mass of chlorine 35 and chlorine 37 ratio of isotopes 3:1

Average atomic mass of Cl =

$\large \sf \frac{35×3+37×1}{3+1} \\ \\ \large \implies \frac{ 105+37}{4} \\ \\ \large \implies \frac{142}{4} \\ \\ \large \implies 35.5$
