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)?

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

2.52 g/cm^3

Density of the rock is 2.7 grams per cubic centimeter.

Step-by-step 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 =

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

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
