Analysis of an unknown sample indicated the sample contained 0.140 grams of N and 0.320 grams of O. The molar mass of the compound was determined to be 92.02 amu. What is the molecular formula of the compound?

The answer is c if i’m not wrong

And a) oxygen i believe

Mistures i think, hope it

So the main goal for the elements is stability which is a complete/full valence shell and typically the magic number for a stable element is 8 valence electron but not always. so elements to the left of the periodic table tend to be way less stable then those on the right, so the elements on the left are much more reactive.
