What is mass and how is it measured (unit)?
Mass is the amount of matter in an object and it is measured in grams (g)
Density = 18 g/mL
Volume = 5 mL
What is Mass = 90 g?
Mass = 250 g
Volume = 100 cm3
What is Density = 2.5 g/cm3?

What is Volume = 100 mL
Draw the Mass, Volume, and Density triangle
Mass on top, volume & density on the bottom
What is the definition for volume and what units is it measured in?
Volume is the amount of space an object takes up and is measured in mL or cm3
Density = 24 g/cm3
Volume = 6 cm3
What is Mass = 144 g?
Mass = 270 g
Volume = 9 mL
What is Density = 30 g/mL
Density = 8 g/mL
Mass = 92 g
What is Volume = 11.5 mL
If an object or substance has a density LESS THAN the density of water (1 g/mL), what will it do?
Float
Definition for density & it is measured in what units
Density is the mass per unit of volume. And it is measured in g/mL or g/cm3
Density = 48 g/mL
Volume = 15 mL
What is Mass = 720 g
Mass = 454 g
Volume = 227 mL
What is Density = 2 g/mL?
Density = 2.5 g/mL
Mass: 1,000 g
What is Volume = 400 mL
If an object or substance has a density GREATER THAN the density of water (1 g/mL), what will it do?
Sink
Definition of matter
What is anything that has mass and takes up space?
When a metal object is dropped into a graduated cylinder, the water level rises from 25 mL to 47 mL. If the density of the metal if 6 g/mL, calculate its mass.
V = 47 mL - 25 mL
V = 22 mL
M = D x V
M = 6 g/mL x 22 mL
M = 132 g
A rectangular prism has a length of 10 cm, a width of 2 cm, and a height of 3 cm. If the mass of the prism is 90 g, determine its density.
V= 10 cm x 2 cm x 3 cm
V = 60 cm3
D= M/V
D= 90g/60cm3
D = 1.5 g/cm3
An object has a density of 1.5 g/cm3 and a mass of 45 g. What is its volume?
V = M/D
V = 45 g/1.5g/cm3
V = 30cm3
