Measurements
What was your favorite part of the density experiment?
:)
LxWxH
What is the formula for volume?
The measurement of how much matter there is in a certain amount of space.
What is the definition of Density?
A liquid has a volume of 4mL and a mass of 24g. What is the density of the liquid?
6 g/mL
What is the density of an object that sinks in water?
Greater than 1.0g/mL
Bonus Points for ONLY your team!
Congratulations on the lucky pick!
A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper?
8.96 g/cm3
What is the density of an object that floats in water?
Less than 1.0g/mL
What is the formula for density?
Mass / Volume
22.95g / 15.45cm. Find density. Say if it sinks or floats.
1.49g/cm. The object sinks.
What is the density of water?
1.0 g/mL
An object has the Mass of 45.87 g and the Volume of 21.42 mL. Find the Density.
2.1414 g/mL
What kind of property of an object is the Mass?
Hint: chemical or physical
A physical property.
970g / 1,070mL . Find the density. Say if it sinks or floats.
0.9 g/mL. This object floats.
Oil and vinegar salad dressings must be shaken to mix them. How is this an example of density?
Hint: Think about our lab
The oil and vinegar have different densities and separate.
4.6g/12.5cm3. Find the density. Does it sink or float?
0.368g/cm3. It floats.
A block of wood 3 cm on each side has a mass of 27 g. What is the density of the block?
1 g/cm3
What kind of substance property is Density?
A Physical Property
Hint: Chemical or Physical
A small rock with a mass of 6g is dropped into a graduated cylinder with 20mL of water. The water rises to 23mL. What is the density of the rock?
2 g/cm3
In an oil spill, the oil floats on top of the water. Why is this?
The oil is less dense than the water.
