Station #10
1. If a liquid sample has a volume of 128.0 mL and a
density of 1.58 g/mL, what is the mass of this liquid
sample?
2. A sample of metal has a mass of 42.80 g and a density of
22.5 g/mL. The sample is placed into a graduated
cylinder that contains 22.5 mL of water prior to putting
in the metal. What will be the new volume reading on
the graduated cylinder after the metal sample is put in?
3. If you have a graph with volume plotted on the x axis
and mass plotted on the y axis, how can you determine
the density for the plotted data?
