Which of the following items would have the highest density?
A. A 2 cm3 block of lead with a mass of 11 grams
B. A 12 cm3 block of wood with a mass of 3 grams
C. A 12 cm3 block of aluminum with a mass of 2 grams
Answer:
Lead has the highest density when compared to wood and aluminum.
Explanation:
Density can be calculated by the given formula
Density= Mass ÷ Volume
Density of Lead = 11gm ÷ 2cc
= 5.5 gm/cc
Density of Wood = 3gm ÷ 12cc
= 0.25 gm/cc
Density of aluminum = 2gm ÷ 12cc
= 0.166 gm/cc
Hence, Lead has the highest density of 5.5 gm/cc.
