- Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 46.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the bone: m3 What is its average density? average density of the bone: kg/m³ about us privacy policy terms of use contact us help careersBird bones have air pockets in them to reduce their weight.

- A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.A block of wood has a mass of 3.71 kg and a density of 515 kg/m3.
