The expected chirp mass distribution of observed events for future
gravitational wave detectors is extensively investigated in the presence
of an exotic fluid component with an arbitrary equation of state,
, i.e., the so-called
dark energy component.
The results for a flat model dominated by dark energy are compared
to those for the standard flat model dominated by cold dark matter.
It is found that for a flat universe the chirp mass distribution
shows a sensitive dependence on 
, which may provide an
independent and robust constraint on the cosmic equation of state.
