Calculating Density

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What are the units commonly used for density in the metric system?

Back

g/cm³ (grams per cubic centimeter) or g/mL (grams per milliliter)

Front

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 does it mean for an object to float in water?

Back

An object floats in water if its density is less than the density of water (1 g/cm³).

Front

What is the density of water?

Back

1 g/cm³ at 4°C.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

If an object has a density of 0.8 g/mL, will it sink or float in water?

Back

It will float because its density is less than that of water.

Front

What is the density of a cube with a mass of 8 grams and a volume of 4 cm³?

Back

2 g/cm³

Front

How can you determine the volume of an irregularly shaped object to calculate density?

Back

By using water displacement method: submerge the object in water and measure the volume of water displaced.

Front

What is the relationship between mass, volume, and density?

Back

Density is a ratio of mass to volume; if mass increases while volume remains constant, density increases.
