Question

Find the value of $x$.

ELEMENT	ATOMIC MASS	MOLECULAR MASS	ATOMICITY
Chlorine	$35.5$	$71$	$2$
Ozone	$16$	$48$	$3$
Sulphur	$32$	$x$	$8$

Answer 1

From given table, molecular mass= atomic mass $\times$ atomicity.

$\therefore x=32\times 8$

$\Rightarrow x=256$

i.e. Molecular mass of sulphur is $x=256$ .
