WebMolar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 10 23 titanium atoms. The characteristic molar mass of an element is simply the atomic mass in g/mol. WebA fictional element has two isotopes and an atomic mass of 131.244 amu.
