                                    Density = --------------     or    D = -------
                                                 Volume                         v

Use the density formula to solve the following problems:

1.  Calculate the density of a material that has a mass of 52.457 g and a volume of 13.5 cm3.

 


 
2.  A student finds a rock on the way to school.  In the laboratory he determines that the volume of the rock is 22.7 cm3, and the mass in 39.943 g.   What is the density of the rock?

 


 
3.  If 30.943 g of a liquid occupy a space of 35.0 ml, what is the density of the liquid in g/cm3?


 

 
Answers     1)    3.89 g/cm3                            2)      1.76 g/cm3                             3)      0.884 g/cm3
