Решить превращение:метан--ацетилен--этилен--этанол--этаналь--уксусная кислота--хлоруксусная кислота

Заранее предупреждаю ответ может быть не правильным.

Найдем массовую долю углерода в октане (масса углерода составляет 12 а.е.м., водорода - 1 а.е.м.):

(12 а.е.м. * 8) / (12 а.е.м. * 8 + 1 а.е.м. * 18) = 96/114

Найдем массовую долю углерода в углекислом газе (масса кислорода составляет 16 а.е.м.):

(12 а.е.м. * 1) / (12 а.е.м. * 1 + 16 а.е.м. * 2) = 12/44

Составим пропорцию:

масса октана = 28.52 г - массовая доля углерода = 96/114

масса углекислого газа = х г - массовая доля углерода = 12/44

Решая пропорцию получаем:

х = 28.52 г * (96/114) / (12/44) = 28.52 г * (176/56) = 89,63 г
