Question

3. Смешали 5л метана и 2л этана. Вычислите объемные доли газов в данной смеси​

Answer 1

Ответ:

Объяснение:

Объемные доли газов равны их мольным долям. ==>
u(CH4) = 5 / 7 * 100 % = 71,43 %
u(C2H6) = 2 / 7 * 100% = 28,57 %

Answer 2

Calculation of Gas Volume Fractions

To calculate the volume fractions of methane and ethane in the given mixture, we need to know the total volume of the mixture and the volumes of methane and ethane in the mixture.

Given: - Volume of methane (CH4): 5 liters - Volume of ethane (C2H6): 2 liters

To find the volume fractions, we can use the following formula:

Volume Fraction = (Volume of Gas / Total Volume) * 100

Let's calculate the volume fractions for methane and ethane:

1. Volume fraction of methane: - Volume of methane: 5 liters - Total volume of the mixture: 5 liters (methane) + 2 liters (ethane) = 7 liters - Volume fraction of methane = (5 liters / 7 liters) * 100 = 71.43%

2. Volume fraction of ethane: - Volume of ethane: 2 liters - Total volume of the mixture: 5 liters (methane) + 2 liters (ethane) = 7 liters - Volume fraction of ethane = (2 liters / 7 liters) * 100 = 28.57%

Therefore, the volume fractions of methane and ethane in the given mixture are approximately 71.43% and 28.57%, respectively.

Please note that the above calculations assume ideal gas behavior and do not take into account any interactions or deviations from ideal gas behavior.
