Question

CH4=75%. C2H6=15%. H2=5% O2?

Answer 1

Ответ:

The percentages you've provided seem to represent the composition of a mixture of gases, including methane (CH4), ethane (C2H6), hydrogen (H2), and you're asking about oxygen (O2).

To find the percentage of oxygen (O2) in the mixture, you need to account for the remaining percentage (100% - 75% - 15% - 5% = 5%). This 5% represents the sum of all other gases, including oxygen. If oxygen is the only remaining gas, then it makes up the entire 5%. However, if there are other gases in the mixture not mentioned, then oxygen's percentage could be lower.

So, based on the information provided, the percentage of oxygen (O2) in the mixture would be 5% or lower, depending on the presence of other gases not mentioned.
