What is the empirical formula of a compound that contains 27.0\% S 13.4\% O and 59.6\% Cl by mass?
S2O5 S 2 O 5
If we consider tetrasulfur decaoxide, S4O10 S 4 O 10 , we can reduce the 4:10 sulfur to oxygen ratio to 2:5. Thus, the empirical formula of this compound is S2O5 S 2 O 5 .
What is the empirical formula of a compound that contains?
An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H2O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H2O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen.
