Answer 1

Basically cause its really abundant and almost always you can find the same amount of Neutrons and protons and electrons inside it. In other words, this element is really abundant and pretty much the most consistent, in reality the mass is not 12, it is 12.something because there are some atoms that do variate, but 99% of the time they are the same.
