An aluminum cylinder (of density 2.70 x 10^3 kg/m^3) weighs 8.0 N, and has a volume of 3.0 x 10^(-4) m^3. If the cylinder is suspended from a scale while completely submerged in a fluid, the scale reading is 5.5 N. What is the density of the fluid?
A. 8.5 x 10^2 kg/m^3.
B. 1.9 x 10^3 kg/m^3.
C. 2.7 x 10^3 kg/m^3.
D. 4.6 x 10^3 kg/m^3.
