Imagine that you performed this experiment as described in your lab manual. In doing so, your first temperature reading was 26 oC , and your second reading was 54 oC . Your first volume was 34 mL . what would be your calculated 2nd volume?

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.
