Объяснение:
Mr(HBr) = 1+80 = 81
W(H) = Ar(H) *n / Mr(HBr) *100% = 1*1 / 81 *100% =1%
W(Br) = Ar(Br) *n / Mr(HBr) *100% = 80*1 / 81 *100% = 99%
Mr(H2SO4) = 1*2 + 32 + 16*4 = 98
W(H) = Ar(H) *n / Mr(H2SO4) *100% = 1*2 / 98 *100% = 2%
W(S) = Ar(S) *n / Mr(H2SO4) *100% = 32*1 / 98 *100% =33%
W(O) = Ar(O) *n / Mr(H2SO4) *100% = 16*4 / 98 *100% = 65%
