Understand that the molar mass of an element is the mass of one mole of its atoms, usually expressed in grams per mole (g/mol).
Locate copper (Cu) on the periodic table, where the atomic mass is typically listed below the element symbol.
Identify the atomic mass of copper, which corresponds to its molar mass in g/mol.
Compare the given options to the atomic mass value found on the periodic table for copper.
Select the value that matches the atomic mass of copper, which represents its molar mass.
