The walking catfish is a species of fish that walks on land using its pectoral fins. During drought conditions, when there is little water in its habitat, the walking catfish can use its
pectoral fins to get to areas with water. Which of these will MOST LIKELY happen to a
population of walking catfish over time if all nearby aquatic environments dry up
permanently?

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.
