The density of copper is 8.94 grams per cm3. The mass will depend on the volume of the "lump" of copper.
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
density = mass/volume = 43.54g / 26.5ml ≈ 1.643 g/ml
density = mass/volume = 250g/45cm3 = 5.6g/cm3 (rounded to 2 sig figs)
The copper's density is 8.9 g/cm3
Its density. Density is mass per unit volume.
The density of copper is 8.94 grams per cm3. The mass will depend on the volume of the "lump" of copper.
Density of a substance = (mass of a sample of it)/(volume of the same sample)
I have no clue. Sorry. :( ^^ Ignore that ^^ I think Density = mass/volume.
Volume of a sample = (its mass) divided by (its density)
The density of this copper mass is about 8.93 g/cm3
volume =mass/ density volume = 55.932/8.92 = 6.27 cm3
Density = mass / volume As sample size increases, both mass and volume increase in the same ratio.
The density of the sample is about 2.14 g/mL
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
