What is the formula for calculating mass number? For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
What is the formula to find the mass? To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
