WORD PROBLEMS (2 pts each)
1.) A block of aluminum occupies a volume of 15.0mL and has a mass of 40.5g. What is its
density?
2.) Mercury metal is poured into a graduated cylinder that holds exactly 22.5mL. The mercury in
the cylinder has a mass of 306.0g. From this information, calculate the density of mercury.

3.) Find the mass of 250mL of benzene that has a density of 0.8765g/mL.
4.) A rectangular block of copper metal has a mass of 1896g. The dimensions of the block are
8.4cm by 5.5cm by 4.6cm. From this data, what is the density of copper? (hint: find the volume of
a block first)
5.) What is the volume of a silver that has a mass of 2500g and a density of 10.5g/cm 3.
6.) A block of lead has dimensions of 4.50cm by 5.20cm by 6.00cm. The block has a mass of
1587g. From this information, calculate the density of lead.
Extra Credit Question (4 pts)
