Apiece of unknown metal with a mass of 17.19 g is heated to 100.00 degrees celsius and is dropped into 25.00 g of water at 24.50 degrees celsius. the final temperature of the water is 30.05 degrees celsius. what is the specific heat of the metal?

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.
