89.2g
25/29.4 = 0.85 grams/cm3
The density is 7.8 grams per cm^3.
Density = Mass/Volume = 16/2.8 g/mL = 5.714 grams per mL (approx).
The density of silver is 10490 kg/m3. You need to have a piece of silver for it to have a mass or volume.
This is clearly a piece of wood that is forcibly submerged since its density would require it to float. So the volume of displaced water should be equal to the volume of the whole piece of wood. Then, density = mass/volume = 62/0.525 g/L = 62/525 g/ml = 0.12 g/ml which is a lot less dense than balsa (0.16 g/ml)!
8.9 grams/mL x 396 mL = 3524.4 grams, or about 3.5 kg
Iron pyrite (FeS2) has a density of 4.8 to 5.0 grams per cm3. A piece of volume 40 cm3 would, therefore have a mass of volume*density = 192 to 200 grams.
Weigh the piece of maple (you've indicated it is about 10 grams) Completely submerge it in a liquid and measure the volume of liquid displaced Density = mass/(volume displaced) or about 10g/(volume displaced)
25/29.4 = 0.85 grams/cm3
The density is 7.8 grams per cm^3.
The density of a piece of granite with a volume of 340 cm and mass of 918 g would be 1,400 grams. This is a math problem.
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
0.3 g/cm2
What metal? There are great variations in density, between different metals - some of them being about 40-50 times denser than others. Choose a metal, look up its density, then use the formula: density = mass / volume. Solving for volume: volume = mass / density.
Density = Mass/Volume = 16/2.8 g/mL = 5.714 grams per mL (approx).
If the volume stay the same, i.e 256 cubic centimeters then the density will be 2.34g/cubic centremeter. However if the the volume changes because it is the same material then the density will be 1.17g/cubic centimeter as calculated by density= mass/volume
It is 2.6 g/cm3.
