Determine molar mass of an element
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. WebAtomic mass in an atom or group of an atom is the sum of the masses of protons, neutrons and electrons. The electrons have very less mass in comparison to protons or neutrons so the mass of electrons is not influenced in the calculation. For an element, relative atomic mass is the average mass of the naturally occurring isotopes of that element ...
