$48, 72$

Vedclass · Answer

(A) For $SO_2$: The molar mass of $S$ is $32 \, g$ and $O_2$ is $32 \, g$. Since $32 \, g$ of $S$ combines with $32 \, g$ of $O_2$,then $48 \, g$ of $S$ will combine with $(32 / 32) 	imes 48 = 48 \, g$ of $O_2$. For $SO_3$: The molar mass of $S$ is $32 \, g$ and $O_3$ is $48 \, g$. Since $32 \, g$ of $S$ combines with $48 \, g$ of $O_3$,then $48 \, g$ of $S$ will combine with $(48 / 32) 	imes 48 = 72 \, g$ of $O_3$. Thus,the masses are $48 \, g$ and $72 \, g$.

In $SO_2$ and $SO_3$,the masses of oxygen that combine with $48 \, g$ of sulfur are respectively ......... .
