Web31 de mar. de 2024 · To find the molar mass, find the atomic mass of all the components of a chemical. You can either memorize it, or find all of the atomic masses located on the periodic table of elements. In this case, hydrogen has an atomic mass of 1, and oxygen has an atomic mass of 16. The equation is therefore: 1 (2) + 16 (1) = 18. do british have thanksgiving
