Question

Using the measurements in the table, determine which undefined metal has the lowest density.

Answer 1

Answer:

Option C. Metal C.

Explanation:

To know which option is correct, we'll begin by calculating the density of each metal.

The density of a substance is simply defined as the mass of the substance per unit volume of substance. It can be expressed mathematically as:

Density = mass /volume.

Now, we shall determine the density of each metal as follow:

Metal A:

Volume = 12.5 cm³

Mass = 122 g

Density =?

Density = mass /volume

Density = 122/12.5

Density = 9.76 g/cm³

Metal B:

Volume = 14.2 cm³

Mass = 132 g

Density =?

Density = mass /volume

Density = 132/14.2

Density = 9.30 g/cm³

Metal C:

Volume = 18.1 cm³

Mass = 129 g

Density =?

Density = mass /volume

Density = 129/18.1

Density = 7.13 g/cm³

Metal D:

Volume = 12.7 cm³

Mass = 126 g

Density =?

Density = mass /volume

Density = 126/12.7

Density = 9.92 g/cm³

Summary:

Metal >>>>>>>> Density

A >>>>>>>>>>>> 9.76 g/cm³

B >>>>>>>>>>>> 9.30 g/cm³

C >>>>>>>>>>>> 7.13 g/cm³

D >>>>>>>>>>>> 9.92 g/cm³

From the above calculations, metal C has the lowest density.
