Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, forming a solution.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per milliliter (g/ml).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

If two objects are made of the same substance, what can be said about their mass and size?

Back

The larger object will have more mass than the smaller object.

Front

Is it true that a heavier piece of iron is always harder than a lighter piece?

Back

False. Hardness is a property that does not depend solely on mass.

Front

What is the unit of measurement for density in chemistry?

Back

The unit of measurement for density is typically grams per milliliter (g/ml).

Front

What does it mean if a substance is denser than another?

Back

It means that the substance has more mass per unit volume compared to the other substance.

Front

What is the relationship between mass and volume for substances of the same type?

Back

For substances of the same type, mass increases with volume.

Front

What is an example of a substance with high solubility?

Back

Sugar in water is an example of a substance with high solubility.

Front

What is an example of a substance with low solubility?

Back
