Question

The density of a certain type of steel is 8.1 g/cm3. What is the mass of a 124 cm3 chunk of this steel? Show
your equation.

Answer 1

Mass of the steel is $1004.4 g$

• density of a substance can be regarded as the ratio of the mass of that substance to that of it's volume.

• Mass of substance can be regarded as the quantitative measure of inertia, it can be simply explained as a fundamental property of all matter

We can express this mathematically as ;

• $Density= \frac{ mass }{volume }$

Given :

Density of this steel= 8.1g/cm3

$Mass= 124 cm^{3}$

If we make Mass subject of formula,

$Mass= ( density *volume)$

Then let us substitute the values into the expression

$Mass= (124*8.1)$

$= 1004.4 g$

Therefore, mass of the steel is $1004.4 g$
