Density = mass/volume = 75g/1500 cm3 = 1/200 g/cm3 = 0.050 g/cm3
That value is half of common balsa wood density (there are other woods that are less dense but your example is rater extreme)
Density = Mass/Volume = 25g / 4 cm3 = 6.25 g/cm3
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).
Density = Mass/Volume = 57.2g/11 cm3 = 5.2 gcm-3
10.5 g cm-3
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)
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.
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).
Density = Mass/Volume = 57.2g/11 cm3 = 5.2 gcm-3
10.5 g cm-3
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.
0.3 g/cm2
Density = Mass/Volume = 16/2.8 g/mL = 5.714 grams per mL (approx).
