Exercise 5 Page 225

Substitute the given values into the density formula.

5 g/cm^3

Practice makes perfect

Let's recall that the density of an object is equal to its mass divided by its volume. density=mass/volume In our exercise we are asked to find the density of an object with a mass of 7.5* 10^3 grams and a volume of 1.5* 10^3 cubic centimeters. Let's substitute these values and evaluate.

density=mass/volume

mass= 7.5*10^3, volume= 1.5*10^3

density=7.5*10^3/1.5*10^3

a/b=.a /10^3./.b /10^3.

density=7.5/1.5

Calculate quotient

density=5

The density of this object is 5g/cm^3.
