Mr(NO2) = 14+16*2 =46
W(N) = Ar(N) *n / Mr(NO2) *100% = 14*1 / 46 *100% =30%
W(O) = Ar(O) *n / Mr(NO2) *100% = 16*2 / 46 *100% = 70%
Mr(H2S) = 1*2 + 32 = 34
W(H) = Ar(H) *n / Mr(H2S) *100% = 1*2 / 34 *100% =6%
W(S) = Ar(S) *n / Mr(H2S) *100% = 32*1 / 34 *100% = 94%
Mr(P2O5) = 31*2 + 16*5 =142
W(P) = Ar(P) *n / Mr(P2O5) *100% = 31*2 / 142 *100% =44%
W(O) = Ar(O) *n / Mr(P2O5) *100% = 16*5 / 142 *100% = 56%
