The mass of one penny is 2.51 grams and its volume is 0.40 cubic centimeter. The density in g/ml of this penny is

density=mass/volume or

volume=mass/density

1.00

1.00 is wrong do not put that as your answer!

6.28

How did u get 6.28

To calculate the density of an object, you need to divide its mass by its volume. In this case, the mass of the penny is given as 2.51 grams and its volume is 0.40 cubic centimeters.

So, to find the density of the penny, you can use the formula:

Density = Mass / Volume

Substituting the given values, we have:

Density = 2.51 grams / 0.40 cubic centimeters

Evaluating this expression, we get:

Density ≈ 6.275 g/cm³

Therefore, the density of this penny is approximately 6.275 grams per cubic centimeter (g/cm³).
