The volume of a sample of water is 20 cm3. The mass of this sample is closest to
That depends what substance you are talking about. You have to multiply the volume by the density of the substance.
80g /20cm3 = 4g/cm3
I have no clue. Sorry. :( ^^ Ignore that ^^ I think Density = mass/volume.
Apparently, the mass of water is simply the difference between saturated soil mass and the dried soil mass and this is 0.25 kg. - grade
Its density. Density is mass per unit volume.
That depends what substance you are talking about. You have to multiply the volume by the density of the substance.
Density = Mass/Volume. Without information about the mass, you cannot calculate the density.
density = mass/volume = 40/20 = 2 g/cc
80g /20cm3 = 4g/cm3
what?
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.
D = M/V Density = Mass/Volume 5 g/cm^3 = Mass/20 cm^3 Mass = 100 g
The volume and the mass of sample both depend on the size of the sample.A small sample has small volume and small mass, a big sample has big volumeand big mass. But the ratio of mass to volume is constant for a pure sample ofa substance, no matter what size the sample is. That ratio is called the densityof the substance.
27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.
Volume of a sample = (its mass) divided by (its density)
