The periodic table includes the atomic weights of all of the elements. The molar mass of an element is its atomic weight in grams/mole (g/mol).


The atomic weight for helium on the periodic table is #4.002602#. The molar mass of of helium is #"4.002602 g/mol"#. This means that one mole of helium has a mass of #"4.002602 g"#.
