The answer is 2.25g/ml or 2.25 g/cm³
To do this, you need to know the formula of density. Density is the mass per unit of volume.
Where:
D = Density
M = Mass
V = Volume
You already have your mass, which is 45.0g, so what is your volume?
A graduated cylinder measures the volume of liquids. The procedure that was done here is called the displacement method. You can get an estimated volume of an irregular object by subtracting the initial volume from the final volume.
In this case, it would be:
<span>70.0mL - 50.0mL = 20.0 mL
</span>
The volume is then 20.0mL.
Now that we have the volume we can solve for density.
Now take note that 1mL = 1cm³. So you can also express the answer as
2.25g/cm³.
