Объяснение:
Mr(NO) = 14+16 =30
W(N) = Ar(N) *n / Mr(NO) *100% = 14*1 / 30 *100% =47%
Mr(HNO3) = 1 + 14 + 16*3 = 63
W(N) = Ar(N) *n / Mr(HNO3) *100% = 14*1 / 63 *100% =22%
Mr(NO2) = 14 + 16*2 = 46
W(N) = Ar(N) *n / Mr(NO2) *100% = 14*1 / 46 *100% = 30%
Mr(NH3) = 14 + 1*3 = 17
W(N) = Ar(N) *n / Mr(NH3) *100% = 14*1 / 17 *100% = 82%
