what is the density of iron if 5.0 cm at the third has a mass o 39.5 grams

density equals mass divided by volume

39.5 grams divided by 5.0 cubic centimeters

7.9 grams per cubic centimeter

To calculate the density of iron, we need to use the formula:

Density = mass/volume

Given:
Mass = 39.5 grams
Volume = (5.0 cm)^3 (since it is a cube)

First, let's calculate the volume:
Volume = (5.0 cm)^3 = 125 cm^3

Now we can calculate the density:
Density = 39.5 grams / 125 cm^3

Density = 0.316 grams/cm^3

Therefore, the density of iron is approximately 0.316 grams/cm^3.

To determine the density of iron, we need to use the formula:

Density = Mass / Volume

Given information:
Mass = 39.5 grams
Volume = 5.0 cm^3 (cubic centimeters)

To find the density, we divide the given mass by the given volume:

Density = 39.5 grams / 5.0 cm^3

Now let's calculate the density:

Density = 7.9 grams / cm^3

The density of iron is approximately 7.9 grams per cubic centimeter.
