A compound has a molar mass of 456.18g/mol and consists pf 3.0g of Fe and 4.81g of S. Calculate both empirical and molecular formulas.​

Sagot :

Answer:

If we divide the known molar mass (283.88 g/mol) by this formula mass (141.94 g/mol) we get 2. Thus the true formula of the compound is twice the empirical formula: (P2O5)2 or P4O10.
