What do you mean to "tell me what the empirical formulas are?" These ARE the empirical formulas.
N2O5 is dinitrogen pentoxide.
Hg2Cl2 is mercury(I) chloride.
C6H12 could be hexane but it could also be a number of other compounds.
C2H6O4 could be one of hundreds of compounds.
C2H6O4-> CH3O2
N2O5-> N2O5
Hg2Cl2-> HgCl
C6H12-> CH2
