검증된 단계별 안내1
Understand that an empirical formula represents the simplest whole-number ratio of atoms of each element in a compound.
Look at each given formula and determine the ratio of atoms for each element.
For C2H4, divide the subscripts by 2 to simplify: C2H4 becomes CH2, which is the empirical formula.
For C6H12O6, divide the subscripts by 6 to simplify: C6H12O6 becomes CH2O, which is the empirical formula.
For H2O2, divide the subscripts by 2 to simplify: H2O2 becomes HO, which is the empirical formula.
