What is the density of water?
1.0g/mL
What is the formula for density?
Define Density...
Density is the amount of matter in a given amount of space (volume). It's a comparison of how much matter to the space it occupies.
Is Density a chemical or physical property of matter?
physical property
What happens if an object's density is greater than 1.0g/mL
the object would sink in water
What are all of the units for density?
g/cm3
g/mL
g/L
What is the definition of Volume?
The amount of space an object takes up.
1.74g/mL X 63mL. Find the mass.
109.62 g
What if an object's density is less than 1.0g/mL?
The object would float in water
How do you solve for Volume of a regular shaped object?
Volume = L x W x H
What is the definition of Mass?
The measurement of the amount of matter in an object.
22.95g / 15.45cm3. Find density. Say if it sinks or floats.
1.49g/cm3. The object sinks.
What is the definition of Weight?
A measure of the amount of matter with the force of gravity acting upon it.
What are the units on a graduated cylinder?
mL or mililiters
An object has the Mass of 45.87 g and the Volume of 21.42 mL. Find the Density.
45.87g/21.42mL = 2.14 g/mL
Honey's density is 2.0g/mL and Rubbing Alcohol's density is 0.85 g/mL. Which liquid would float on top and which liquid would sink down beneath the other?
Rubbing alcohol float on top of honey because RA less dense and Honey more dense making it sink
41g / 3.2g/mL. Find the volume.
12.81mL.
What does the density of water help us do?
Helps us make comparisons to see if objects would sink or float
4.6g/12.5mL. Find the density. Does it sink or float?
0.368g/mL. It floats.
An object has the mass of 4.67g and Volume of 3.91 mL. What is the Density?
Density = 4.67/3.91 = 1.19g/mL
An object has the Density of 12.36 g/mL and the Mass of 6.52 g. What is the Volume?
80.59mL
Compare the cm3 and mL
what makes them related/connected/similar?
