Density Practice

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate the volume of an object?

Back

Volume can be calculated using the formula: Volume = Mass / Density.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 150 grams and a density of 11.3 g/cm³, what is its volume?

Back

13.3 cm³.

Front

What is the density of a substance with a mass of 42 grams and a volume of 6 cm³?

Back

7 g/cm³.

Front

How do you find the mass of a substance if you know its volume and density?

Back

Mass can be found using the formula: Mass = Density x Volume.

Front

What is the mass of a substance with a volume of 72.5 cm³ and a density of 0.94 g/cm³?

Back

68.2 grams.

Front

What does it mean if an object floats 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 significance of significant figures in measurements?

Back

Significant figures indicate the precision of a measurement and should be used in calculations to reflect that precision.

Front

How do you determine the volume of an irregular object using water displacement?

Back

The volume of an irregular object can be determined by measuring the change in water level when the object is submerged.
