One cubic centimeter (1.0 cm3) of water has a mass of 1.0 ✕ 10-3 kg.
(a) Determine the mass of 1.0 m3 of water.

Correct: Your answer is correct.
kg

(b) Assuming biological substances are 98% water, estimate the masses of a cell with a diameter of 1.1 µm, a human kidney, and a fly. Take a kidney to be roughly a sphere with a radius of 3.7 cm and a fly to be roughly a cylinder 3.7 mm long and 2.4 mm in diameter. (Enter your answer using one of the following formats: 1.2e-3 for 0.0012 and 1.20e+2 for 120.)
