Answer:
Density =mass/Volume
First of all let's find the mass
= 2.5 ×102kg
= 225kg
Then the volume
=4.1 × 103 m3
=422.3m3
225kg /422.3m3
=0.53279659
The density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3 will be 6.03 kg/m³ .
What do you mean by the density of a substance ?
Density is defined as the ratio of mass of the object to the volume of the object. Different substances have different densities.
The mathematical expression for density is as follows:
Density=Mass/Volume
The mass of a substance is expressed in kilograms and the volume is expressed in liter.
Thus, the unit of density is kg L⁻¹.
The density of a substance does not depend on the amount of the matter.
Thus, density is an intensive property.
To calculate the density -:
Given,
Mass= 2.5 ×102 kg=2550 kg
Volume=4.1 × 103 m³=422.3m³
Density=mass/volume
Density=2550/422.3
Density=6.03kg/m³
Hence, 6.03kg/m³ is the density of a piece of metal .
