Question

Визначити молекулярну формулу насиченого вуглеводню, відносна густина парів якого за воднем 57.

Answer 1

Ответ:

C8H18

Объяснение:

Насыщенные углеводороды имеют общую формулу СnH2n+2

Находим молярную массу соединения 57*2=114 г/моль

Подставляем в формулу и решаем уравнение

12n+1*(2n+2)=114

12n+2n+2=114

14n=112

n=8

C8H18

Answer 2

Determining the Molecular Formula of a Saturated Hydrocarbon

To determine the molecular formula of a saturated hydrocarbon with a relative density of vapor compared to hydrogen of 57, we can use the information provided in the search results.

The relative density of vapor compared to hydrogen is a measure of the molecular weight of the compound. In this case, the relative density is 57. This means that the molecular weight of the compound is 57 times that of hydrogen.

To find the molecular formula, we need to consider the atomic weight of hydrogen and calculate the molecular weight of the compound.

According to the search results, the relative density of vapor compared to hydrogen is 57 However, the search results do not provide the atomic weight of hydrogen or any other specific information about the compound. Therefore, we cannot determine the molecular formula of the saturated hydrocarbon based solely on the information provided.

To determine the molecular formula, we would need additional information such as the atomic weight of hydrogen and the specific composition of the compound.
