2. construct explanations assume that one particular atom of rhodium (rh) has a mass of 102. why does this number not exactly match the atomic mass of 102.91 listed on the periodic table for this element?

2. construct explanations assume that one particular atom of rhodium (rh) has a mass of 102. why does this number not exactly match the atomic mass of 102.91 listed on the periodic table for this element?

Answer

Brief Explanations:

The atomic mass on the periodic table is a weighted - average of all the isotopes of rhodium. The mass of 102 is likely the mass of a single isotope, while the 102.91 is an average considering the relative abundances of all rhodium isotopes.

Answer:

The atomic mass on the periodic table is a weighted - average of all isotopes of rhodium, while 102 is likely the mass of a single isotope.
