Question
Define the empirical formula of a compound asthe simplest whole number ratio of the differentatoms or ions in a compound
Solution
The empirical formula of a compound is defined as the simplest, most reduced ratio of atoms present in a compound. It represents the relative amounts of different elements in a substance. Here are the steps to determine the empirical formula:
-
Identify the elements present in the compound and the number of atoms of each element.
-
Convert the number of atoms of each element to moles. This is done by dividing the mass of each element by its atomic mass.
-
Divide the number of moles of each element by the smallest number of moles calculated in step 2. This will give you the simplest whole number ratio of the atoms.
-
If the ratios are not whole numbers, they may need to be multiplied by a factor to achieve whole numbers. This factor is usually 2, 3, or 4.
-
The empirical formula is then written using these simplest whole number ratios. For example, if the ratio of hydrogen to oxygen is 2:1, the empirical formula would be H2O.
