Question

1. A 24.50 g piece of metal displaces 2.6 ml of water. Calculate the density of the

metal?

Answer 1

Answer:

9.42g/cm3

Explanation:

Data obtained from the question include the following:

Mass of the metal = 24.50g

Volume of metal = 2.6 ml = 2.6cm3

Density =..?

The density of a substance is defined by the mass of the substance per unit volume of the substance. It is represented mathematically as:

Density = Mass /volume

With the above formula, we can obtain the density of the metal as follow:

Density = Mass/volume

Density = 24.50g/2.6cm3

Density = 9.42g/cm3

Answer 2

Answer:

$\rho =9.42g/mL$

Explanation:

Hello,

In this case, this is an example of Archimedes principle in which we can compute the density of metal by means of the displaced volume a mass does, in this case, 24.50 g displaced 2.6 mL of water, thus, the density turns out:

$\rho =\frac{m}{V}=\frac{24.50g}{2.6mL}\\ \\\rho =9.42g/mL$

Best regards.
