Britney found an irregularly shaped metal object on the beach that has a mass of 232.5 grams. To determine the volume, she partially filled a cylindrical water bottle and dropped the object in. The water level in the bottle rose by 1.2 cm. The bottle has a diameter of 5 cm. Calculate the density of the metal to determine what type of metal Britney found. Densities, measured in grams per cubic centimeters, g cm3 , for some common metals are listed.

The question is incomplete, the complete question is;

Britney found an irregularly shaped metal object on the beach that

has a mass of 232.5 grams. To determine the volume, she partially

filled a cylindrical water bottle and dropped the object in. The

water level in the bottle rose by 1.2 cm. The bottle has a diameter

of 5 cm. Calculate the density of the metal to determine what type

of metal Britney found. Densities, measured in grams per cubic

centimeter, g

cm3

, for some common metals are listed.

• Copper: 8.86 g

cm3

• Bronze: 9.87 g

cm3

• Silver: 10.5 g

cm3

• Gold: 19.3 g

cm3

Select the word that correctly completes the sentence.

Based on the density of the metal, it is most likely that the metal Britney

found is .

\ copper

\ bronze

\ silver

\ gold

Bronze: 9.87 g

bronze

Explanation:

We know that the volume of the liquid = the volume of the object

This is because the object will cause the liquid to occupy its own volume of the container.

Now; area of the container = πr^2 = 3.142 * (5/2)^2 = 19.635 cm^2

Volume of the liquid = volume of the sold = 19.635 cm^2 * 1.2 cm= 23.562cm^3

Now given that;

Density = mass/volume = 232.5 g/23.562cm^3 = 9.87 g/cm^3

it is the most commonly accepted one
