Question

During laboratory investigation, students determined a large block of iron to have a density of 7.75 g/mL. If the block were to be cut in half, what would be the density of the smaller block?

a. 7.75 g/mL
b. 15.5 g/mL
c. 3.88 g/mL
d. 5.58 g/mL

Answer 1

Answer: (a) 7.75 g/mL

Explanation: Density is calculated as mass/volume. When you cut the block in half, you cut the mass in half and the volume in half, meaning that the density is the same.

EX: 2/2 = 1; also 1/1 = 1
