(a)
Interpretation: The metal that occupies larger volume from lead, Pb and iron Fe needs to be determined.
Concept Introduction:
The density of a substance is related to its mass and volume as follows:
Here, m is mass and V is volume.
(a)
Answer to Problem 9E
Iron, Fe occupies larger volume than lead, Pb.
Explanation of Solution
The mass and volume is related to density as follows:
Here, it is given that mass density of lead Pb is more than iron Fe and both have same mass that is 4.3 g.
For same mass, the density is inversely related to the volume thus, volume of iron Fe will be larger and it must occupy more space than lead Pb.
(b)
Interpretation: The metal with larger mass needs to be determined.
Concept Introduction:
The density of a substance is related to its mass and volume as follows:
Here, m is mass and V is volume.
(b)
Answer to Problem 9E
The metal with larger mass is lead Pb.
Explanation of Solution
The mass and volume is related to density as follows:
Here, it is given that mass density of lead Pb is more than iron Fe and both have same volume that is 2.6 mL.
For same volume, the density is directly related to the mass thus, mass of lead Pb will be more than iron Fe.
