The table below shows the age of fossils found in four separate layers of an undisturbed rock: Fossils In Rock Layers Layer Fossil in Layer Age of Fossil (million years) A W 550 B X 240 C Y 680 D Z 450 Which is the topmost layer of the rock? (4 points) Layer A Layer B Layer C Layer D

answer; /// i believe that the correct answer is (50%);

cuz he's blad

explanation:

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.

i think its y= -4x-14
