Density Calculation Practice

Front

What is the formula for calculating density?

Back

D = M/V, where D is density, M is mass, and V is volume.

Front

How do you calculate the volume of an object if you know its mass and density?

Back

Use the formula V = M/D.

Front

If a key has a mass of 59.5 grams and displaces 7 ml of water, what is its density?

Back

D = M/V = 59.5g / 7ml = 8.5 g/ml.

Front

What is the density of a cube with a mass of 50 grams and a volume of 10 cc?

Back

D = M/V = 50g / 10cc = 5 g/cc.

Front

If you know the density and volume of an object, how can you find its mass?

Back

Use the formula M = D x V.

Front

What does it mean if an object has a density greater than 1 g/ml?

Back

It means the object will sink in water.

Front

What does it mean if an object has a density less than 1 g/ml?

Back

It means the object will float in water.

Front

What is the unit of density in the metric system?

Back

Common units include grams per milliliter (g/ml) or grams per cubic centimeter (g/cc).

Front

How can you determine what material an object is made of using density?

Back

By comparing the calculated density of the object to known densities of materials.

Front

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

Back

Density is the ratio of mass to volume.
