Mr[C2H4O2] = Ar[C] * 2 + Ar[H] * 4 + Ar[O] * 2 = 12.0107 * 2 + 1.00794 * 4 + 15.9994 * 2 = 60.05196 = 60

Массовая доля углерода (C) = 24.0214 : 60.05196 * 100 = 40.001 %

Массовая доля водорода (H) = 4.03176 : 60.05196 * 100 = 6.714 %

Массовая доля кислорода (O) = 31.9988 : 60.05196 * 100 = 53.285 %
