Density Calculations
If the density of Material A is equal to 2.5 g/cm3 and the density of Material B is = to 1.0 g/cm3 which of them would be water?
What is Material B
The original block of Material A is cut into 10 equal pieces. When compared to the density of the original block, what will happen to the density of the original piece?
What is it will stay the same, density never changes.
What is the density of water?
What is water 1 g/cm3
What is the unit used for measuring density?
What is g/cm3
A piece of wood has a density of 1.1 g/cm3 and a volume of 55 cm3; what is the wood's mass?
What is 60.5 grams
If a substance has a density of 9.5 g/cm3, it will do THIS when you put it in water
What is it will sink
Is ice more dense than water? Explain how you know.
What is no, ice is less dense than water because it floats in water
What is the unit used for measuring mass?
What is grams or kilograms
An unknown sample has a density of 6.0 g/cm3. If the sample was cut in half, what would be the density of each half?
What is 6.0 g/cm3
How can you find the volume of an irregularly-shaped object? (What is the name of the process?)
What is water displacement
In a density column, where does the most dense liquid go?
What is at the bottom
What are the units for measuring volume?
What is milliliters or cubic cm (cm3)
True or False: If an object sinks in water and you know its volume is 30 mL, its mass is 1 g.
What is false; its mass must be more than 30 g to have a density that is greater than 1 g/cm3
A rectangular block of copper metal weighs 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, what is the density of copper?
8.92 g/cm3

6.32 cm3
The formula for density is
What is mass divided by volume

What is 2 cm3 or 2 mL
A 34.5 g gold nugget is dropped into a graduated cylinder containing water. The density of gold is 19.3 g/cm3. If the water in the cylinder began at 50 ml, what marking will the water level rise to when the nugget is completely covered?
51.78 ml . (About 52 ml)
Is helium less dense than air? How do you know?
What is yes because a helium balloon rises in air
