Answer:
EMPIRICAL FORMULA - In chemistry, the empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfuric dioxide, S₂O₂
MOLECULAR FORMULA - A molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. ... The molecular formula for a compound can be the same as or a multiple of the compound's empirical formula.
