Measurements
What is the density of water?
1.0g/mL
What is the formula for density?
Mass / Volume
What is the definition of Density?
The measurement of how much mass of a substance is contained in a given volume.
The mass of an object is 4.67g and its volume is 32.8mL. Find Density and say if it sinks or floats.
0.14g/mL. The object sinks.
What can Density do when identified?
It can identify an unknown substance.
What is the density of an object that sinks in water?
Greater than 1.0g/mL
What is the formula for volume?
Mass / Density
What is the definition of Volume?
The amount of space an object takes up.
If an object has a density of 1.74g/mL and a volume 63mL. Find the mass.
109.62g
When measuring the Volume of a solid object, what unit is it usually expressed in?
In cubic centimeters.
What is the density of an object the floats in water?
Less than 1.0g/mL
What is the formula for mass?
Density X Volume
What is the definition of Mass?
the measurement of the amount of matter in an object.
If an object has a mass of 22.95g and a volume of 15.45cm3. Find density. Would it sink or float?
1.49g/cm3. The object sinks.
What is the definition of Weight?
A measure of mass and the force of gravity.
What units are used for density?
grams per milliliter or grams per cubic centimeters
