Объяснение:
Mr(N2O3) = 14*2 + 16*3 = 76
W(N) = Ar(N) *n / Mr(N2O3) *100% = 14*2 / 76 *100% = 37%
W(O) = Ar(O) *n / Mr(N2O3) *100% = 16*3 / 76 *100% = 63%
Mr(ZnCl2) = 65 + 35,5*2 = 136
W(Zn) = Ar(Zn) *n / Mr(ZnCl2) *100% = 65*1 / 136 *100% = 48%
W(Cl) = Ar(Cl) *n / Mr(ZnCl2) *100% = 35,5*2 / 136 *100% = 52%
