In some cases yes, the Empirical Formula and Molecular Formulas can be the same.

Explanation:

The Empirical Formula is the lowest whole number ratio of atoms that form the formula of a molecule.

#CO_2# #1:2#
#H_2O# #2:1#
#CH_4# #1:4#
#C_1H_2O_1# #1:2:1#

The Molecular Formula is that actual numbers of atoms that make up the molecule.

#CO_2# #1:2#
#H_2O# #2:1#
#C2H_8# #1:4#
#C_6H_12O_6# #1:2:1#
