A piece of aluminum has a mass of 39.15g and a volume of 14.5cm cube. Determine the density of the aluminum. What would the density be of a much larger piece of aluminum? explain.
I established the density of the al. is 2.7g/ cm cube.
I don't get the second part of the question?

how did you get that? please explain as well. I'd appreciate it
To determine the density of the aluminum, you need to divide the mass of the aluminum by its volume. In the given information, we know that the mass of the aluminum is 39.15g and the volume is 14.5 cm³. So the density can be calculated as:
Density = Mass / Volume
Density = 39.15g / 14.5cm³
Density = 2.7 g/cm³
Now, regarding the second part of the question, if we are considering a much larger piece of aluminum, the density would still be the same. The density of a material is an intrinsic property and does not depend on the size or amount of the material. So, regardless of whether the piece of aluminum is small or large, the density of aluminum will remain constant at 2.7 g/cm³.
To determine the density of an object, you need two pieces of information: its mass and its volume. The formula to calculate density is:
Density = Mass / Volume
For the given piece of aluminum with a mass of 39.15g and a volume of 14.5cm³, we can find its density by dividing the mass by the volume:
Density = 39.15g / 14.5cm³ ≈ 2.7g/cm³
Now, let's address the second part of the question: "What would the density be of a much larger piece of aluminum?"
The density of a substance remains constant regardless of the object's size or amount. This means that the density of a much larger piece of aluminum would still be the same as the initial piece, which is 2.7g/cm³.
Density is an intrinsic property of a material. It does not depend on the mass or volume of the substance. So, whether you have a small piece or a larger piece of aluminum, the density will remain constant as long as the material remains the same.
