Question

A wooden piece of Volume 20CM3 has a mass of 130g .find the
density of wooy.

​

Answer 1

Density = Mass/ volume

=130g/20cm^3

=6.5 gcm^3

Answer 2

Question:-

A wooden piece of volume 20cm³ has a mass of 130g . find the density of wood

Solution:-

Given:-

Volume ( v ) = 20cm³

Mass ( M ) = 130g

To find

Density = ?

Formula

Density = Mass/ volume

Now , put the value on formula

Density = 130g / 20cm³

Density = 6.5g/cm³

Now convert into kg / m³

6.5 g /cm³ = 6.5 x 10³ kg/ m³

So density of wood is 6.5 × 10³ kg/m³

Key Concepts

=> Density is a characteristic property of a substance.

=> The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).

=> The mass of atoms, their size, and how they are arranged determine the density of a substance.

=> Density equals the mass of the substance divided by its volume; D = m/v.

=> Objects with the same volume but different mass have different densities.
