Mixture of Gases: Composition & Properties

[MMCS]

Attached is the question and my working, my answers don't match up to the given answers, but they still seem right. Can anybody see where the mistake is?

 

[Sunil Simha]

Your calculations look alright to me but an expert's view on the matter will be definitely welcome. Have you asked your professor?

 

[Borek]

I don't see anything wrong about your numbers.

 

[MMCS]

Ok thanks. The answers provided are the ones given by the professor, ill assume he has made an error.

I would first like to clarify that there can be multiple correct answers in a scientific context, and it is important to critically evaluate and analyze the data to arrive at the most accurate and reliable conclusions.

In regards to the question about the composition and properties of a mixture of gases, it is important to first understand the definition of a mixture. A mixture is a combination of two or more substances, where each substance retains its own physical and chemical properties.

In the context of gases, a mixture can be composed of different gases such as oxygen, nitrogen, carbon dioxide, and others. The composition of a gas mixture is determined by the relative amounts of each gas present in the mixture. This can be expressed in different ways, such as mole fraction, mass fraction, or volume fraction.

Now, in terms of the properties of a gas mixture, they can vary depending on the specific gases present in the mixture. However, some general properties of gas mixtures include pressure, temperature, volume, and density. These properties can be calculated using the ideal gas law, which states that the pressure, volume, and temperature of a gas are related by the equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature.

In conclusion, the composition and properties of a gas mixture can be determined by analyzing the relative amounts of each gas present and using the ideal gas law to calculate its properties. It is important to carefully analyze the data and consider all factors to arrive at accurate conclusions.
