Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that

mixas84 [53]

Answer:

mas of water displaced = 41.4 g

Explanation:

Weight in air = True weight = 45 g

Apparent weight = 3.6 g

Apparent weight = True weight - Buoyant force

Buoyant force = 45 g - 3.6 g = 41.4 g

Weight of water displaced = Buoyant force

Weight of water displaced = 41.4 g dyne

mas of water displaced = 41.4 g

If the mass of a material is 120 grams and the volume of the material is 23 cm3, what would the density of the material be?

oee [108]

The density is 5.22 g/cm³.

Density= $\frac{mass}{volume}$
Density= $\frac{120 g}{23 cm {3} }$
Density= 5.22 g/cm³
