Question

An unknown material has a mass of 5.75 g and a volume of 7.5 cm3.
What is the density of the material? Round to the nearest tenth.
A. 0.8 g/cm3
B. 8 g/cm3
C. 0.7 g/cm3
D. 1.3 g/cm3

Answer 1

Hey there!:

Mass = 5.75 g

Volume = 7.5 cm³

Therefore:

Density = mass / volume

D = 5.75 / 7.5

D = 0.7 g/cm³

Answer C

Hope that helps!

Answer 2

Answer:

8 g/cm3

Explanation:

The formula for density is density = mass/volume, or d = m/v.

Simply plug the mass and volume into the formula to find the density:

d = 5.25 g/7 cm3

d = 0.75 g/cm3

Rounding to the nearest tenth gives:

b = 0.8 g/cm3
