Can a chemical formula be identical to its empirical formula? Certainly. Remember that the empirical formula is the simplest ratio of atoms in a molecule. In some cases, the molecular formula cannot be simplified further.
Can the molecular formula be the same as the empirical formula? Molecular formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound’s molecular formula cannot be reduced any more, then the empirical formula is the same as the molecular formula.
When can we say that the molecular formula is same as empirical formula? A molecular formula is the same as its empirical formula if, in the molecular formula, the ratio of the number of each atom in the formula is non-reducible. That is to say, there is no common (whole number) factor between the subscripts on the atoms in the formula.
Can empirical formulas be different? The molecular formula for a compound is equal to, or a whole-number multiple of, its empirical formula. Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers.
