16) D- DMV (Dept of Motor Vehicles) Density=mass divided by volume 17) D- DMV or MVD (mass= volume x density) 18) D- DMV or VDM (volume=density divides mass) V= density mass
Science
What is density? Density is the amount of matter (mass)you have crammed in a given space (volume) The unit for mass is grams (mg or g or kg) Unit for solid volume is cubic meters (cm3 or m3 or km3) Unit for liquid volume is liters (mL or L or kL) Units for density is g/cm3 or g/mL
To compute density - divide the mass by the volume of the object

Use this formula: Density = mass divided by volume
NotesSPI 0807.9.7
Density Science
Density= volume mass
Example: The mass of an object is 30g and the volume is 10cm3
What is the density? Do the math: 30 (mass) divided by 10 (volume)
Density = 10 30
D= M/V or orMV
D=
Units…g/cm3
Density = 3 g/cm3

A different formula:Not DMV…instead use MVD
Mass = Volume x Density
NotesSPI 0807.9.7
Density Science
Example: The volume of an object is 10cm3. The density of the object is 3 g/cm3
What is the mass?
Do the math: 10 (volume) times 3 (density)
Mass = 10 x 3
M= V x D
Units…gramsMass = 30 g

A different formula:Not DMV…instead use VDM
Volume = Density divides the Mass
NotesSPI 0807.9.7
Density Science
Example: The density of an object is 3 g/cm3.
The mass of the object is 30 g. What is the volume?
Do the math: 30 (mass) divided by 3 (density)
V= D M
Units…cm3
Volume = 3 30 Volume = 10 cm3 10
