To calculate the mass of a higher number of moles, or even calculate the mass of a certain number of moles, a formula triangle can be used. The formula mass of calcium carbonate can be calculated using the formula and values from the data book. The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23. The relative atomic mass of each element shown in the data book is calculated from the masses of all the isotopes of an element taking into account the percentage proportion of each.


Calculate the number of protons, electrons and neutrons.Atomic number Z -11Atomic mass A - 23No.
Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to the number of electrons.
