Science uses data to describe the findings of an experiment. Qualitative Data is: A. set of knowledgeable explanations for a certain phenomena
B. set of data describing the findings of an experiment
C. set of data using numbers or measurements to represent the findings of an
experiment
D. experimental sample absent
experimental sample absent of the factor in question

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.
