Мr(C2H4O2) = Ar(C) * 2 + Ar(H) * 4 + Ar(O) * 2 = 12 * 2 + 1 * 4 + 16 * 2 = 60
w(C) = Ar(C) * n/ Мr(C2H4O2) * 100% = 12 * 2/60 * 100% = 40%
w(H) = Ar(H) * n/Мr(C2H4O2) * 100% = 1 * 4/60 * 100% = 6,67%
w(O) = Ar(O) * n/Мr(C2H4O2) * 100% = 16 * 2/60 * 100% = 53,33%
Mr(C4H8O2) = Ar(C) * 4 + Ar(H) * 8 + Ar(O) * 2 = 12 * 4 + 1 * 8 + 16 * 2 = 88
w(C) = Ar(C) * n/ Мr(C2H4O2) * 100% = 12 * 4/88 * 100% = 54,54%
w(H) = Ar(H) * n/Мr(C2H4O2) * 100% = 1 * 8/88 * 100% = 9,1%
w(O) = Ar(O) * n/Мr(C2H4O2) * 100% = 16 * 2/88 * 100% = 36,36%
