$20$

Vedclass · Answer

(B) The equivalent weight of an element is defined as the mass of the element that combines with $8 \ g$ of oxygen or $1 \ g$ of hydrogen or $35.5 \ g$ of chlorine or $80 \ g$ of bromine.Given that $1 \ g$ of calcium combines with $4 \ g$ of bromine.Therefore,the amount of calcium that combines with $80 \ g$ of bromine is calculated as:$	ext{Equivalent weight of } Ca = \frac{1 \ g \ Ca}{4 \ g \ Br} 	imes 80 \ g \ Br = 20 \ g$.Thus,the equivalent weight of calcium is $20$.

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

$1 \ g$ of hydrogen combines with $80 \ g$ of bromine. $1 \ g$ of calcium (valency $= 2$) combines with $4 \ g$ of bromine. The equivalent weight of calcium is ...
