По-хорошему для начала стоило бы написать уравнение реакции, однако точной формулы угля нет в силу его разнообразности. Антрацит + O2 ->t-> некий остаток + CO2 «Чистая» же реакция выглядит следующим образом: C + O2 ->t-> CO2 10 г угля и 18 л CO2... Так, для начала посчитаем количество молей углекислого газа: разделим 18 л на молекулярный объём равный 22,4 л. Получим примерно 0,8 молей CO2. Теперь нам нужна молярная масса углерода: обратимся к таблице Менделеева! Молярная масса С = 12 г/моль. Умножим 12 на 0,8 и получим массу карбона (углерода) в данном соединении – 9,6 г. Массовая доля карбона в угле 9,6/10, 96%!
