What unit is used to calculate density?
g/cm3
What is the term that something can float?
Positive Buoyancy
An object has a mass of 50 g and a volume of 25 cm³. What is its density?
2 g/cm3
Volume is measured in these units for solids.
cm3
What is the formula used to find mass?
M= Density X Volume
What is the amount of matter in a object?
Mass
What is the term for an object that sinks.
Negative buoyancy
If an object has a density of 0.8 g/cm³, what will it do in water?
Float
Which is larger: 1 L or 500 mL?
1 L
If mass increases but volume stays the same, what happens to density?
Density Increases
What is the amount of space an object takes up?
Volume
What is the term for an object that does not float or does not sink?
Neutral Buoyancy
What is the formula for density?
Density = Mass ÷ Volume
Mass = 40 g Density = 4 g/cm³
Volume = __________
10.0 cm³
If density = 2 g/cm³ and volume = 5 cm³, mass = ?
10 g
If you know density and volume, what can you calculate?
Mass
How dense is fresh water?
1.00 g/cm3
Mass = 102 g Volume = 13 cm³
7.8 g/cm³
Mass = 22 g Density = 2.5 g/cm³
Volume = __________
8.8 cm³
Density = 6.3 g/cm³ Volume = 4.7 cm³
Mass = __________
29.6 g
Why does a huge ship made of metal float?
Because it displaces enough water to match its weight, lowering its overall density below 1.0 g/cm³.
If two objects displace the same amount of water, they must have the same:
Volume
Mass = 56 g Volume = 11 cm³
5.1 g/cm³
Mass = 72.4 g Density = 9.1 g/cm³
Volume = __________
8.0 cm³
2.8 g/cm³ Volume = 10.2 cm³
28.6 g
