Equation for finding molar mass

WebOne mole (abbreviated mol) is equal to 6.022×10 23 molecular entities (Avogadro’s number), and each element has a different molar mass depending on the weight of 6.022×10 23 of its atoms (1 mole). The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table.
