Dinitrogen monoxide (n20; nitrous oxide) is a greenhouse gas that enters the atmosphere principally from natural fertilizer breakdown. some studies have shown that the isotope ratios of,5n to mn and of l80 to i60 in n20 depend on the source, which can thus be determined by measuring the relative abundance of molecular masses in a sample of n20. (a) what different molecular masses are possible for n20? (b)the percent abundance of mn is 99.6%, and that of 160 is 99.8%. which molecular mass of n20 is least common, and which is most common?

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
