What is definition of volume?
Amount of space matter occupies
What is the formula for density?
Mass/Volume
You have a slice of pizza. You take a few bites of the slice of pizza. Did the density of the pizza change?
No, the mass changed because you ate it, and the volume changed because you ate it, but that keeps the density the same.
What do we use for the units of volume when measuring a regular-shaped solid?
cm3
Mass= 20 g
Volume= 20 cm3
Density= 1 g/cm3
What tool is used to measure mass with 3 sets of weights?
triple beam balance
What is the formula to for volume of a solid?
Length x Width x Height
Metal has a volume of 15cm^3 and a density of 3.0g/cm^3. What would its mass be?
45 g
What do we use for the units of mass?
grams (g)
Mass= 23 g.
Volume= 20 mL
Density= 1.15 g/mL
What tool is used to measure liquid volume?
graduated cylinder
What is the formula for volume when density is given?
Mass/Density
A shoe box has a volume of 500.00cm^3 and mass of 750.0 grams. What is it's density?
1.5 g/cm^3?
What do we use for units of liquid volume?
mL
Mass = 5g
Volume = 20 mL
Density = 0.25g/mL
What is the definition of mass?
The amount of matter in an object
What is the formula for mass?
Denstiy X Volume
A liquid has a mass of 24g and a density of 2.0g/mL. What is its volume?
12 mL
What do we label with these units? g/mL or g/cm3
Density of an object
Mass = 3 g.
Volume = 14 cm3
Round your answer to the nearest hundredth.
Density = 0.21 g/cm3
What is the definition of density?
The amount of matter in a given volume
How do you calculate the volume of a cube? (this is really more of a math question!)
side x side x side or s3
A pencil is floating in liquid A. Another pencil (of the same volume and mass) has sunk in liquid B. Use the terms density to make a comparison between liquid B and A.
Liquid B must be less dense than liquid A.
What is 1 cubic centimeter equal to in mL?
1 mL
Mass = 2 g.
Volume = 21 cm3
Round to the nearest hundredth.
Density = 0.10 g/cm3
