For the acids, use the formula pH = -log(H') (Because HCI has 1 H ion per formula unit, (H) equals the
molarity.) For water, use what you know about the pH of neutral solutions. For the bases, examine and
extend the pattern. DONE

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.
