Assume the given amount of RbF fully dissociates in water. Calculate the molarity of a solution if 184.75 g of RbF are dissolved into a solution of water that has a final volume of 1.00 L.

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.
