The density of a material can easily be calculated if we are given the mass and volume of a sample
2
In this example, we’re given that a 230 mL sample of butter has a mass of 200 g and we’re asked to calculate the density of butter in grams per centimeter cubed. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3.
3
We know that the formula for density is density equals mass divided by volume. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume The density formula
4
We’ll make a note of the mass and volume in a table here A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3
5
The mass of the sample is 200 g A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3
6
And because mL is a unit of volume, we can state that the volume of the sample is 230 mL A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3
7
However, we notice that they want us to calculate the density in grams per centimeter cubed, or grams per cubic centimeter. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 2 cm 3 The unit of density required is g/cm 3
8
So the unit we use for volume needs to be centimeters cubed. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = = 2 cm 3 The unit of density required is g/cm 3
9
It is known that 1 mL is the same volume as 1 centimeter cubed. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = = 2 cm 3 1 mL = 1 cm 3 230 mL = 230 cm 3
10
So 230 mL is the same as 230 centimeters cubed A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 1 mL = 1 cm 3 230 mL = 230 cm 3
11
And we can put 230 in for the volume in centimeters cubed. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 1 mL = 1 cm 3 230 mL = 230 cm 3
12
Now we can substitute the values for mass and volume into our equation, density equals mass divided by volume A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 density = mass volume
13
We substitute 200 grams in for mass A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 density = 200 g volume
14
And 230 centimeters cubed in for volume A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 density = 200 g 230 cm 3
15
So the density is 200 grams divided by 230 centimeters cubed, A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 density = 200 g 230 cm 3
16
Which comes out to 0.87 grams per centimeter cubed. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 density = 200 g 230 cm 3 density = 0.87 g/cm 3
17
So the answer to the question is the density of butter is 0.87 grams per centimeter cubed. A 230 mL sample of butter has a mass of 200 g. Calculate the density of butter in g/cm 3. density = mass volume mass200 g volume 230 mL = 230 cm 3 density = 200 g 230 cm 3 density = 0.87 g/cm 3 The density of butter is 0.87 g/cm 3 Answer
