Front

What is density?

Back

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

Front

How does density affect whether an object sinks or floats in water?

Back

An object will float if its density is less than that of water (1 g/mL) and sink if its density is greater than that of water.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is the formula to calculate mass from density and volume?

Back

Mass = Density × Volume.

Front

If an object has a density of 0.6 g/mL, what will happen when it is placed in water?

Back

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

Front

What is the density of water?

Back

The density of water is approximately 1 g/mL at 4°C.

Front

How do you arrange liquids in order of density?

Back

To arrange liquids by density, compare their densities; the liquid with the highest density will be at the bottom.

Front

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

Back

Density is a ratio of mass to volume; as mass increases with constant volume, density increases.

Front

What happens to an object with a density of 10.07 g/mL when placed in water?

Back

It will sink because its density is greater than that of water.

Front

If a material has a density of 2 g/cm³ and a volume of 24 cm³, what is its mass?

Back

The mass is 48 grams (Mass = Density × Volume = 2 g/cm³ × 24 cm³).
