Theempiricalformulafor thecompoundP₄O₆ is "P2O3."The empirical formula of a compound represents the simplest whole number ratio of theelementsin the compound. To determine the empirical formula from the molecular formula (P₄O₆ in this case), you need to find the greatest common factor (GCF) between the subscripts of the elements. In P₄O₆, the GCF between the number ofphosphorusatoms (4) and the number of oxygen atoms (6) is 2.By dividing both subscripts by 2, you arrive at the simplest whole number ratio: P₂O₃. This means that in thecompoundP₄O₆, there are two phosphorus atoms for every three oxygen atoms. The empirical formula P₂O₃ represents this ratio in the most simplified form. It is essential to note that the molecular formula may have multiple of these empirical units (n x P₂O₃), but the empirical formularepresentsthe core ratio of the elements in the compound.To learn more aboutempirical formula, herebrainly.com/question/32125056#SPJ12...
