Vedclass · Answer

(A) The average atomic mass is calculated using the weighted average of the isotopes:$	ext{Average atomic mass} = \sum (	ext{abundance}_i 	imes 	ext{mass}_i)$$	ext{Average atomic mass} = (0.7577 	imes 34.9689) + (0.2423 	imes 36.9659)$$	ext{Average atomic mass} = 26.4972 + 8.9567 = 35.4539 \ u$Rounding to appropriate significant figures,the average atomic mass of chlorine is approximately $35.45 \ u$.

Isotope	Natural abundance (%)	Molar mass $(u)$
$^{35}Cl$	$75.77$	$34.9689$
$^{37}Cl$	$24.23$	$36.9659$

Calculate the average atomic mass of chlorine using the following data:

Isotope Natural abundance (%) Molar mass $(u)$

$^{35}Cl$ $75.77$ $34.9689$

$^{37}Cl$ $24.23$ $36.9659$
