Ответ:Массовое отношение атома углерода к атому кислорода в углекислом газе CO2 можно определить, зная молекулярную массу CO2 и зная, что она содержит один атом углерода и два атома кислорода.

Молекулярная масса CO2 = масса атома углерода (C) + 2 * масса атома кислорода (O)

Так как масса атома углерода равна 75 % массы атома кислорода, можно записать это отношение следующим образом:

Масса атома углерода (C) = 0.75 * Масса атома кислорода (O)

Теперь мы можем заменить массу атома углерода в молекулярной массе CO2:

Молекулярная масса CO2 = 0.75 * Масса атома кислорода (O) + 2 * Масса атома кислорода (O)

Молекулярная масса CO2 = 0.75 * Масса атома кислорода (O) + 2 * Масса атома кислорода (O) = 0.75 * Масса атома кислорода (O) + 2 * 0.25 * Масса атома кислорода (O) = 0.75 * Масса атома кислорода (O) + 0.5 * Масса атома кислорода (O) = 1.25 * Масса атома кислорода (O)

Теперь мы знаем, что молекулярная масса CO2
