Atomic mass of nitrous oxide?
Nitrous Oxide is not an element, therefore it doesn't have atomic mass. An element is a substance in the form of solid, liquid, gas or metalloid, which can not be broken down anymore. For example, Tin is not an element because it is made up of different elements. Oxygen is just oxygen it is not made out of anything but oxygen atoms. :) BTW I'm a 8th grader that learned this is Science class and made a 102 on the test of the periodic table, elements and the atoms that make them up.
