A piece of metal (mass = 18.300 g)is placed in 11.00 mL of chloroform (d = 1.498 g/mL)in a 25-mL graduated cylinder.The chloroform level increases to 15.46 mL.The best value for density of this metal from these data is
A)1.18 g/mL.
B)2.74 g/mL.
C)4.103 g/mL.
D)6.15 g/mL.
E)4.10 g/mL.

Quizplus · Accepted Answer

The density of the metal is calculated as follows:Density = mass / volumemass = 18.300 gvolume = 15.46 mL - 11.00 mL = 4.46 mLDensity = 18.300 g / 4.46 mL = 4.103 g/mLThe best value for the density of this metal from these data is 4.103 g/mL.
