WebSo using our formula for calculating percentage by mass from above we would need the following information: Relative atomic mass of sodium = 23. Number of atoms in the element = 1. Relative formula mass = 84. By putting that information into our formula we would have the calculation. 23 x 1/84 x 100 = 27.38%. This would mean that the … WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number. A property closely related to an atom’s mass number is its atomic mass.
