8.9 grams/mL x 396 mL = 3524.4 grams, or about 3.5 kg
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
Volume cannot be 29.4 cm since that is a measure of a length, not volume. Assuming that you meant 29.4 cm3, the density is mass/volume = 25.0 g / 29.4 cm3 = 0.850 grams per cubic centimetre (to 3 dp).
Because d=M/V the answer is 1,45 g/cm3.
Volume = Mass / Density, so 100 grams of gold divided by 19.3 g/mL gives a volume of 5.18 mL or 5.18 cubic centimeters. 5.18 mL of gold will displace 5.18 mL of water.
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
8.9 grams/mL x 396 mL = 3524.4 grams, or about 3.5 kg
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
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
89.2g
It is 2.6 g/cm3.
