Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less thanthat of the bones of other animals. suppose an ornithologist weighs a bird bone in air and in water and finds its mass is45.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). (a) what mass of water is displaced? (b)what is the volume of the bone? (c) what is its average densim

41.4 g

41.4 cm³

1.08695 g/cm³

Explanation:

= Density of water = 1 g/cm³

Mass of water displaced will be the difference of the

Mass of water displaced is 41.4 g

Density is given by

So, volume of bone is 41.4 cm³

Average density of the bird is given by

The average density is 1.08695 g/cm³
