Density, Mass and Volume

Front

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

Back

Mass = Density × Volume

Front

What is the density of an object if its mass is 60 grams and its volume is 20 cm³?

Back

Density = Mass / Volume = 60 g / 20 cm³ = 3 g/cm³

Front

Define density in terms of mass and volume.

Back

Density is defined as the mass of an object divided by its volume (Density = Mass/Volume).

Front

What is the SI unit for density?

Back

The SI unit for density is kilograms per cubic meter (kg/m³).

Front

How do you convert grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³)?

Back

To convert g/cm³ to kg/m³, multiply by 1000 (1 g/cm³ = 1000 kg/m³).

Front

What is the volume of an object with a density of 2.5 g/cm³ and a mass of 50 grams?

Back

Volume = Mass / Density = 50 g / 2.5 g/cm³ = 20 cm³.

Front

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

Back

Mass is directly proportional to volume when density is constant; as mass increases, volume increases.

Front

What instrument is commonly used to measure the volume of liquids?

Back

A graduated cylinder is commonly used to measure the volume of liquids.

Front

What does the term 'matter' refer to in science?

Back

Matter refers to anything that has mass and occupies space (volume).

Front

If an object has a mass of 12.0 grams, what does this measurement represent?

Back

This measurement represents the mass of the object.
