Gray-banded kingsnakes are endangered species which are most vulnerable to private and commercial pet dealers. new mexico has laws to protect them, which will remain in effect for at least three years. after that time, if a large enough population of gray-banded kingsnakes are present throughout the state and there are provisions for protecting them, the snake will be considered a(n) a) exotic species b) protected species c) endangered species d) threatened species

the answer would be D

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
