How percentage n2gas on air
how is typing in the question here any easier than typing it in on google? You will find many correct responses.
I am not certain of the meaning of your question. The word "How" troubles me.
I think considering her name, it is likely that English is not her native language.
Considering the key words, it is likely that "what" was meant.
Although if I were a non-native speaker of English, I'd take care to post the question exactly as asked.
Of course, it is also possible that the class assignment was given in garbled English as well, in which case a whole other set of problems arises :-)
To calculate the percentage of nitrogen gas (N2) in air, we need to know the composition of air and the percentage of nitrogen gas in that composition.
The air we breathe is composed of several gases, primarily nitrogen (N2), oxygen (O2), and trace amounts of other gases such as carbon dioxide (CO2), argon (Ar), and others.
The percentage of nitrogen gas in air is approximately 78%. This means that 78% of the air we breathe is nitrogen gas.
To calculate the percentage of nitrogen gas in air:
1. Determine the mole fraction of nitrogen gas (N2) in air:
- Multiply the percentage of nitrogen gas (78%) by its mole fraction in air (0.78).
2. Convert the mole fraction to a percentage:
- Multiply the mole fraction (0.78) by 100 to obtain the percentage of nitrogen gas in air.
So the percentage of nitrogen gas in air is 78%.
Keep in mind that this is an approximate value, as the composition of air may vary slightly depending on location and other factors.
