One cubic centimetre (1.0 cm3) of water has a mass of 1.0 × 10−3 kg. (a) Determine the mass of

Question

1.0 litre of water. Assuming that biological substances are 98% water, estimate the masses of (b) a cell with a diameter of 1.0 μm, (c) a human kidney, and (d) a fly. Assume the cell to be spherical, take a kidney to be roughly a sphere with a radius of 3.5 cm and a fly to be roughly a cylinder 3.8 mm long and 1.7 mm in diameter.

Answer 1

a. 0.03L = 1 oz.
L = 33.4 oz.

M = 0.454kg/16oz * 33.4oz = 0.948 kg.
