Tardigrade Admin · Accepted Answer

Average atomic mass of chlorine = (3×35+37×1 /4) = 35.5

Q. For every one $^{37} Cl$ isotope there are three $^{35} Cl$ isotopes in a sample of chlorine. What will be the average atomic mass of chlorine?

$35$

$37$

$35.5$

$35.6$

Average atomic mass of chlorine
$= \frac{3 \times 35 + 37 \times 1}{4} = 35.5$
