Question

A piece of steel has a volume of 12 cm^3 and a mass of 96 g. What is the density in:
(i) g/cm^3
(ii)kg/m^3

Answer 1

Answer:

• Density of steel piece = 8 g/cm³ = 8000 kg/m³

Explanation:

Given

• Volume of steel piece, V = 12 cm³
• Mass of steel piece, M =96 g

To find

• Density of steel piece in g/cm³ and kg/m³, D =?

Formula required

• Formula to calculate density

       D = M / V

[ Where D is density, M is mass and V is volume ]

Solution

We are given, Volume in cm³ and mass in g

so, calculating density of Steel piece in g/cm³

Using formula to calculate density

→ D = M / V

→ D = ( 96 g ) / ( 12 cm³ )

→ D = 8 g/cm³

Therefore,

• Density of steel piece in g/cm³ unit will be 8 g/cm³.

Converting density in g/cm³ into kg/m³

→ D = 8 g/cm³

→ D = 8 ( 1 g ) / ( 1 cm )³

[ since 1 g = 1/1000  kg and 1 cm = 1/100  m, therefore, ]

→ D = 8 · ( 1/1000 kg ) / ( 1/100  m )³

→ D = 8 · ( 100 )³ / 1000

→ D = 8 · ( 1000000 ) / 100

→ D = 8000 kg/m³

Therefore,

• Density of steel piece in kg/m³ unit will be 8000 kg/m³.
