Question

Difference between sodium chloride and naphthaleneon the basis of vapour density

Answer 1

Density is how closely packed matter is within an object.

If one object is denser, its matter is more closely packed into the space.

The object on the left is denser than the object on the right.

Calculating Density

Use the density triangle.

Density=MassVolume

Volume=MassDensity

Mass=Density×Volume

Volume Units

For solids: usually cubic centimeters (cm³).

For gases and liquids: usually milliliters (mL) or liters (L).

Important:

1 mL = 1 cm³ and 1 L = 1 dm³

Density from Mass and Volume

Density=MassVolume

Example:

What is the density of a loaf of bread that has a mass of 500 g and a volume of 1000 cm3?
