One cubic centimeter of water has a mass of 1.00 x 10-3 kg.
(a) Determine the mass of 1.00 m3 of water.
(b) Biological substances are 98% water. Assume that they have the same density as water to estimate the masses of a cell that has a diameter of 1.0 µm, a human kidney, and a fly. Model the kidney as a sphere with a radius of 4.0 cm and the fly as a cylinder 4.0 mm long and 2.0 mm in diameter
