Вычислить массовую долю калия в соединении . kcl=? kclo=? kclo2=? kclo3=? kcl04=?

M(KCL)=74.5 g/mol
W(K)=39/74.5*100%=53.35%

M(KCLO)=90.5 g/mol
W(K)=39/90.5*100%=43.09%

M(KCLO2)=106.5
W(K)=39/106.5*100%=36.62%

M(KCLO3)=122.5 g/mol
W(K)=39/122.5*100%=31.84%

M(KCLO4)=138.5 g/mol
W(K)=39/138.5*100%=28.16%
