Question

Jeremy wants to know the density of a rock in grams per cubic centimeter. The rock has a mass of 1.08 kilograms and a volume of 400 cubic centimeters.

What is the density of the rock, in grams per cubic centimeter (g/cm^3)?

Answer 1

Let's convert the units first.

1.08 kg * (1000 g)/(1 kg) = 1008 g

density = mass/volume

density = 1008 g / 400 cm^3

density = 2.52 g/cm^3

Answer: 2.52 g/cm^3

Answer 2

Density of the rock is 2.7 grams per cubic centimeter.

Explanation:

Jeremy wants to know the density of a rock in grams per cubic centimeter.

The rock has mass M = 1.08 kilograms

Since 1 kilogram = 1000 grams

Therefore 1.08 kilograms = 1.08×1000 = 1080 grams

Volume of the rock is given as V = 400 cubic centimeters

Now we know the formula of Density =
`(mass)/(volume)=(M)/(V)=(1080)/(400)=2.7`

Therefore density of the rock is 2.7 grams per cubic centimeter.
