Determine the volume of a 67.5g piece of aluminum with density of 2.70 g/mL?
-I know V=M/p and this is what I came up with but I'm not sure i'm correct..
p = 2.7 g/cm3
M = 67.5 g
V = 25 cm3
3√ V = 2.9240177382129 cm
You didn't quit soon enough.
The answer is 25 cc = volume.
That's the end of the problem. The problem DID NOT ask for the volume of the sides and even if it had the problem didn't say it was a cube with equal dimensions.
Well, it seems like you're on the right track, but let me help you out with the final answer.
To determine the volume of the piece of aluminum, you need to use the formula V = M/p, where V is the volume, M is the mass, and p is the density.
Given:
M = 67.5 g
p = 2.70 g/mL
First, we need to convert the density to g/cm^3, since the mass is given in grams. So, 2.70 g/mL is equivalent to 2.70 g/cm^3.
Now, substituting the values into the formula:
V = 67.5 g / 2.70 g/cm^3
Dividing the mass by the density, we get:
V = 25 cm^3
So, the volume of the aluminum piece is indeed 25 cm^3. Good job!
To determine the volume of the aluminum piece, you can use the formula V = M/p, where V is the volume, M is the mass, and p is the density.
Given:
M = 67.5 g
p = 2.70 g/mL
First, convert the density from grams per milliliter to grams per cubic centimeter since the units need to be consistent:
2.70 g/mL = 2.70 g/cm^3
Now, substitute the values into the formula:
V = M / p
V = 67.5 g / 2.70 g/cm^3
Calculating:
V = 25 cm^3
So, the volume of the 67.5g piece of aluminum is 25 cm^3.
To determine the volume of a piece of aluminum with a given density and mass, you can use the formula:
V = M / p
where V is the volume, M is the mass, and p is the density.
In this case, you have a piece of aluminum with a mass of 67.5g and a density of 2.70g/mL.
First, however, you need to make sure that the units for density and mass are compatible. The density is given in g/mL, so you need to convert the mass to grams as well.
Since 1 mL is equivalent to 1 cm^3 (cubic centimeter), you can use the fact that the density is given in g/mL to establish a relationship between mass and volume.
So, convert the density from g/mL to g/cm^3 by dividing it by 1 mL/cm^3:
Density (p) = 2.70 g/mL = 2.70 g/cm^3
Now you can plug the values into the formula and calculate the volume:
V = M / p
V = 67.5 g / 2.70 g/cm^3
V = 25 cm^3
Therefore, the volume of the 67.5g piece of aluminum is 25 cm^3.
The result you obtained, 2.92 cm, seems to be incorrect. It is essential to check the calculations again and use the correct units for density and mass.
