A 35.0 mm x 75.0 mm piece of aluminum density 2.70 gcm3 is 0.80 mm thick What is the mass in grams of the metal?

To do this, you need to know what density is. Mathematically, density is mass divided by volume or:
D = m/v
Now all we need to do is replace the density and mass variables to find the volume.
D = 2.70 g/cm3
m = 3.057 kg = 3057 g
2.70 = 3057/v
v = 1130 cm3

∙ 12y agoThe sheet has a volume of 1.35 cm3. So, multiplying it by the density will give you the weight.
45cm x 30cm x 0.0010cm = 1.35cm3
Density x Volume = Mass
2.7g/cm3 x 1.35cm3 = 3.645g
Thus, there is 3.645g of aluminum (assuming that it is a pure product).

What is the density of a 25 gram piece of metal that has a volume of 10 cm cube?
Density= mass/volume 25/10 = 2.5 g/cm3
A piece of magnesium weighs 27.5 g and occupies 13.7 Centameter3 what is the density of the piece of metal?
2.01 g/cm3 density equals mass over volume. so 27.3g/13.7cm^3 = 2.01 g/cm^3 Your welcome!!!
A piece of aluminum foil 0.550 mm thick and 1.00 cm square is allowed to react with bromine to form aluminum bromide A How many miles of aluminum were used The density of aluminum is 2.699 g cm3?
The answer will depend on how much bromine it reacted with or how much auminium bromide was produced. Since this information is not provided, it is not possible to answer the question.
The density of a small piece of matter and a large piece of matter of the same matter are?
If the material is pure and homogeneous, i.e. "the same throughout", then the density is independent of the size of the sample. A chip the size of a pinhead and a chunk the size of a truck have the same density.
What is the density of an unknown metal that has a mass of 1158 g and a volume of 20 mL?
Density is calculated by dividing mass by volume. One mL is the same as 1 cm3. D = m / V = 1158 / 20 = 57.9 g/cm3 You can now use a reference table to determine what the metal might be, or if you know what the metal is you can use a reference table of metal densities to compare the values. If your value, 57.9 g/cm3 is different from the reference value then your piece of metal is not pure. I am assuming that this metal is imaginary as its density is almost 3 times that of gold and more than 5 times that of lead.
What are 4 physical properties of a piece of aluminum foil?
Malleable, brittle, ductile
What is the density of a 25g piece of metal that has a volume of 10 cm cubed?
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
How the density of a large piece of aluminum compare to a small piece?
The same.
A piece of metal weighs 13.21g When inserted into a cylinder containing exactly 50.00mL of water the metal and water occupy a volume of 54.89 mL what is the metal?
Well, the density of the metal is 2.701 g/mL, which I hope is what you're actually asking for. There's not enough information to determine what element the metal is, however.
What is the density of a piece of metal that has a mass of 6.29 times 10 to the power of 5 grams and is 96.4 cm times 49.1 cm times 81.7cm?
The density of this hypothetical metal will be 155,8 g/cm3.
What is the density of a piece of metal that has a mass of 16g and a volume of 2.8 mL?
Density = Mass/Volume = 16/2.8 g/mL = 5.714 grams per mL (approx).
What materials you need to find the density of aluminum?
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
Which has the greatest density a small piece of aluminum or a large piece of aluminum?
density has nothing to do with the size of an object in the way that you are thinking, density is the mass or weight of an object per unit of measurement Neither
How much does a piece of metal weigh?
That would vary greatly depending on the type and density of the metal, along with the dimensions of the particular piece. The weight of a piece of anything is the volume times the density.
What are physical properties of a piece of aluminum foil?
A piece of aluminum foil has a fixed mass and volume, it is flexible, and it is a metal that can conduct electricity.
What is the density of a metal if you cut it in half and the original density was 8.4?
The density is the ratio of mass to volume. It doesn't matter what size the piece of metal, if it is the same metal it has the same density, 8.4.
What is the density of 12.0 cm3 piece of metal with a mass of 5 grams?
Density = mass/volume = 5/12 = 0.4166... gms per cm3. This figure is well below the density of lithium, the least dense of metallic elements.
