The image shows particles of salt dissolved in water. How will the arrangement of salt particles most likely change? Salt particles will move toward the left through diffusion. Salt particles will move toward the left through active transport. Salt particles will move toward the right through diffusion. Salt particles will move toward the right through active transport.

not sure if this what   you'r looking for would be percent composition

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.
