Select the correct answer. a sea is a common resource between two countries. conservation of marine resources is an issue that these countries are facing. which type of approach should the countries adopt to manage their common resource? a. adaptive management b. ecosystem-based management c. community-based management d. integrated management

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.
