A chemist mixes two ideal liquids A and B to form a homogeneous mixture. The densities of the liquids are 2.0 g/mL for A and 3 g/mL for B. When she drops a small object into the mixture, she finds that the object becomes suspended in the liquid. If the mixture is made of 40 percent A and 60 percent B by volume, what is the density of the object?

A

2.60 g/mL

B

2.50 g/mL

C

2.40 g/mL

D

1.50 g/mL
