General Chemistry (Chem101)

A chemist mixes two liquids A and B to form a homogeneous mixture. The densities of the liquids are 2.0514 g/mL for A and 2.6678 g/mL for B. When she drops a small object into the mixture, she finds that the object becomes suspended in the liquid; that is, it neither sinks nor floats. If the mixture is made of 41.37 percent A and 58.63 percent B by volume, what is the density of the object?
I know density = mass/volume, but I can't seem to form a relationship between all these variables. Any help is greatly appreciated :]
General Chemistry (Chem101) -
density of mixture is
.4137*2.0514 + .5863*2.6678 = 2.413g/mL
so, the density of the object is the same
