A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
The chemical formula of sodium hydroxide is NaOH.
depends, an Empirical formula will always (by definition) show the ratio in which atoms are combined within a molecule. a molecular formula on the other hand shows the number of atoms of each element in a molecule, the only exceptions being massive structures, crystal latices and where a molecular formula cannot be produced and is either given in the form n*(empirical formula) or just the empirical formula. do note however that reference to a formula of a molecule usually refer to the molecular formula except in the exceptions listed above.
To determine the empirical formula of a compound, you need the molar masses of its elements and their ratio in the compound. Calculate the ratio of the elements in terms of whole numbers, which will give you the empirical formula.

The definition of dinsity is wieght
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
formula of copper sulphate anhydrous
To build a compound from a chemical formula, first identify the elements present in the formula. Then, determine the ratio of each element in the compound. After that, use this information to arrange the atoms in the correct structure following the rules of chemical bonding.
