Mr(HNO3)=1+14+16*3 = 63
W(O) = Ar(O) * n / Mr(HNO3) *100% = 16*3 / 63 *100% = 76%
Mr(Ag2O) = 108*2 + 16 = 232
W(O)=Ar(O) * n / Mr(Ag2O) *100% = 16*1 / 232. *100% = 7%
Mr(KOH) = 39+16+1=56
W(O)= Ar(O) * n / Mr(KOH) * 100% = 16 *1 / 56 *100% = 29%
Mr(Ca3(PO4)2 = 40*3 + 31*2 + 16*8 = 310
W(O) = Ar(O)*n / Mr(Ca3(PO4)2) *100% = 16*8 / 310 *100% = 41%
