Question

A piece of copper with a volume of 100cm3 has a mass of 890 g. Explain how you could use this information to find out how much mass would be in 13cm3 of copper.

Answer 1

115.7g

Step-by-step explanation:

Given parameters:

Volume of copper = 100cm³

Mass of copper = 890g

Unknown:

Mass of 13cm³ copper = ?

Solution:

We know that the two materials are both made up of copper. Since we know the mass and volume of the first one, let us solve for the density. Using the density of the first one, we can determine the mass of the second one by the given volume.

Density is an intrinsic property of matter. It has the same value for every given substance.

It is expressed as mass per volume of a substance;

Density =
`(mass)/(volume)`

Input the parameters and solve;

Density =
`(890)/(100)` = 8.9g/cm³

Now to find the mass of the 13cm³ copper;

Mass = density x volume

Mass = 8.9 x 13 = 115.7g
