Dr. Flores would like an update on your research about what happened to the lake on Titan. Did the lake on Titan evaporated or froze ? After you clearly state your claim (can be found above), explain how the evidence connects to the claim to support your argument. Remember to explain what happened at both the macro (what we see with our eyes/photos) and molecular scale (what we cannot see at the molecular level). Word bank: freedom of movement, evaporation,.molecule, freezing, phase change, temperature, kinetic energy energy

the answer to your question is b

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.
