Calculating Density

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What units are commonly used to express density?

Back

g/cm³ or g/mL

How do you calculate the volume of an irregularly shaped object?

Back

By using water displacement method.

If an object has a mass of 10 grams and a volume of 5 cm³, what is its density?

Back

2 g/cm³

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

The density increases.
