Answer:
Density,
Explanation:
It is given that,
Mass of an unknown liquid, m = 20.5 g
The volume of unknown liquid is 25 mL
We need to find the volume of the brass object. Mass per unit volume of an object is called its density.
We know that, 1 mL = 1 cm³
So, 25 mL = 25 cm³
Putting the values, we get :
So, the density of this substance is
