A sample of metal pellets weighs 13.54 g. When this sample was placed in a 100-mL graduated cylinder, which contained 25.5 mL water, the new volume (of water and pellets combined) was 27.0 mL. If the metal is one of the solids listed in Table 1, what is the identity of the metal? Show your calculations and use the correct rules for determining significant figures in calculations as shown in the background section. Explain your identification.

Calculate the volume of metal
Volume of metal = 27.0 mL – 25.5 mL = 1.5 mL = 1.5 cm3
Calculate the density of metal = (Mass)/(volume) = (13.54 g)/(1.5 cm3) = 9.026 g/ cm3
Density of metal = 9.026 g/ cm3 = 9.03 g/ cm3 (three significant figures)
Actually, table of metal is not gi...
