HgO, SO2, B2O3, H2O
Объяснение:
Mr(B2O3) = 11*2 + 16*3 =70
W(O) = Ar(O) *n / Mr(B2O3) *100% = 16*3 / 70 *100% = 68%
Mr(HgO) = 200 + 16 = 216
W(O) = Ar(O) *n / Mr(HgO) *100% = 16*1 / 216 *100% =7%
Mr(H2O) = 1*2 + 16 =18
W(O) = Ar(O) *n / Mr(H2O) *100% = 16*1 / 18 *100% =89%
Mr(SO2) = 32 + 16*2 = 64
W(O) = Ar(O) *n / Mr(SO2) *100% = 16*2 / 64 *100% = 50%
