WebWe should then convert these grams into moles, to do so we require the molar mass of the solute, and dividing the given mass (in grams) by the molar mass provides us with the moles of the substance. Therefore, we have everything we need, we have calculated the moles, and we are already given the Molarity (M). 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.
