What is the molarity in 650. ml of solution containing 63 grams of NaCl

it should be all of them because it asks if you included all of those in your answer

explanation:

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.  

the correct answer would be b) volume versus temperature, because they are also directly proportional.
