Question 4 Use the Ideal Gas Equation PV = nRT to solve each problem. Convert to Kelvin.

At what temperature will 0.0714 mol of chlorine exert a pressure of 900 atm at a volume of 750 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.
