Trong KMnO4 :
\(\%O = \dfrac{16.4}{39+55+16.4}.100\% = 40,51\%\)
Trong KClO3 :
\(\%O = \dfrac{16.3}{39+35,5+16.3}.100\% = 39,18\%\)
Trong KNO3 :
\(\%O = \dfrac{16.3}{39+14+16.3}.100\% = 47,52\%\)
MKMnO4 = 158 (đvc)
%O = 64/158 * 100% = 40.51%
MKClO3 = 122.5 (đvc)
%O = 48/122.5 * 100% = 39.18%
Trong KMnO4 :
%O=16.439+55+16.4.100%=40,51%
Trong KClO3 :
%O=16.339+35,5+16.3.100%=39,18%
Trong KNO3 :
%O=16.339+14+16.3.100%=47,52%
Trong: KMNO4
%MO4 =(16.4):(39+55+16.4).100%=40,51%
như trên ta có:trong KCIO3:39,18%
KNO3:47,52%
