If the solubility of sodium acetate (molar mass = 82 g /MOL ) is 76 g per 100 grams of water, which of the following solutions would be considered supersaturated

particle   p is an electron and particle q is a neutron

what is the question here. i think you messed up.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
