Density
A measure of how much mass is contained in a given volume.
Density = Mass divided by Volume
To calculate Density, we use the equation:
d=M/V
To calculate Mass, we use the equation:
M=dV
To calculate Volume, we use the equation:
V=M/d
Density is useful in _________ a substance
identifying
Different substances have ________ densities at specific temperature ranges
different
Density is useful to determine if a substance will sink or ____ in a given liquid.
float
Given:
d = ?
M = 150 g
V = 50 mL
What is the density?
Solution:
d = M/V
d = 150 g / 50 mL
d = 3 g/mL
The density is 3 g/mL.
Given:
M = ?
d = 200 g/mL
V = 5 mL
What is the Mass?
Solution:
d = M/V
M = dV
M = (200 g/mL)(5 mL)
M = 1000 g
The Mass is 1000 g.
Given:
V = ?
M = 150 kg
d = 600 kg/m³
What is the Volume?
Solution:
d = M/V
V = M/d
V = 150 kg / 600 kg/m³
V = 0.25 m³
The Volume is 0.25 m³.
