What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³). It determines whether an object will float or sink in a liquid.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout, meaning that the different components are not distinguishable.

Front

What is a heterogeneous mixture?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.
