Compound formula mass is the atomic mass number of all atoms present in the formula. Therefore, in the same manner as in the use of the emblem elements, a formula is used to indicate a compound and compound units. The mass formula of compounds can be shown easily on the basis of its chemical formula. Recall that such set of formulas that can refer to the free atoms, molecules, or a combination of atoms in ionic compounds, the formula mass term can refer to the atomic mass of an atom, molecule mass of a molecule, or formula mass of an ionic compound.
Compound chemical formula describes the relative number of moles of various elements. If the chemical formula of unknown ionic compound, chemical formula can be estimated from the ratio determined experimentally. This procedure can be done because if the relative mass of elements is obtained, the relative number of moles of each element can be known. Chemical formula derived in this way is called an empirical formula. In solving problems that have been known constituent composition.
If there are more than two elements, the number of mole-mole of the element with the smallest number of moles to obtain the comparison round. Even after this step, we might just have to multiply by a certain small integers to obtain a more rounded comparison more and more small round. So we will get the empirical formula of the compound.
