Question

Массовая доля неизвестного газа, находящегося в смеси с оксидом углерода (IV), равна 12%, а объёмная доля - 60%. Определите, какой это газ. ПОЖАЛУЙСТА

Answer 1

Ответ:

Объяснение:

Пусть m смеси = 100 г
m(CO2) = 0,88 * 100 = 88 г. , а m(неизв.газа) = 12 г.
n(CO2) = 88 / 44 = 2 моль.
Объемные доли газов равны мольным долям газов.
40% = 2 моль.
60% = x моль.
x = 3 моль.
M(неизв.газа) = 12/3 = 4 г/моль. Значит газ = He

Answer 2

Identification of Unknown Gas in Mixture with Carbon Dioxide (IV)

To determine the unknown gas in the mixture with carbon dioxide (IV), we are given that the mass fraction of the unknown gas is 12% and the volume fraction is 60%.

Unfortunately, the search results provided do not contain any relevant information to identify the unknown gas. Therefore, we cannot determine the specific gas based on the given information.

To accurately identify the unknown gas, we would need additional information such as the molecular weight or density of the gas, or more details about the mixture and its properties.

If you have any additional information or context, please provide it so that we can assist you further.
