%element:

$\tt \%=(Ar* subscript)/(Mr)$

Ag₂O:

$\tt \%Ag=(108* 2)/(232)=93.1\%\\\\\%O=(16)/(232)=6.9\%$

KClO₃:

$\tt \%K=(39)/(122.5)=31.8\%\\\\\%Cl=(35.5)/(122.5)=29\%\\\\\%O=(16* 3)/(122.5)=39.2\%\\\\or\:100-(31.8+29)=39.2\%$

SO₃:

$\tt \%S=(32)/(80)=40\%\\\\\%O=(16* 3)/(80)=60\%$

CCl₄:

$\tt \%C=(12)/(154)=7.8\%\\\\\%Cl=(35.5* 4)/(154)=92.2\%\\\\or\:100-7.8=92.2\%$
