An emergency medical responder (emr) quickly checks the breathing and pulse of a patient with alzheimer's disease who has been sleeping outside in the cold for several hours. the emr informs you that the patient grimaces to painful stimuli but is not breathing and does not have a pulse. your best response would be:

the correct answer is c   with the systems

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.
