The density of the marble is about 4.94 g/cm3
density=mass/volume
When pressure increases the volume of the material decreases. Density=mass/volume When volume decreases density increases.(Mass constant)
Assuming it is a round marble (spherical actually) one first has to weigh it. Next one has to measure its diameter using a micrometer or a vernier scale. Halve the diameter to obtain the radius R. The volume can then be calculated by using the equation 4/3 x pi x R x R x R. Pi can be taken as being 22/7 or 3.142 Density is mass divided by volume and on the surface of the earth, mass and weight are usually regarded as being the same (not strictly true but near enough)
We know the size (volume) of the planet AND its mass. Density is mass divided by volume.
Density is a characteristic of a given material. Water, for example, has a certain density (which is somewhat dependent upon temperature but let's say that the temperature is constant). It does not matter how much water you have, it will all have the same density. One teaspoon has much less mass, but the same density as an entire ocean.
the rock has a greater volume than the marble
What do you want to measure about the marble? Its diameter, radius, circumference, volume, mass, density...?
Since density is mass per unit volume, the density is the same.
The density of the marble would be determined by dividing the marble's mass (12.5 g) by its volume (5ml), which would give you 2.5g/ml.

There are several methods:From geometry and the formula for the volume of a sphere:Assuming the marble is a perfect sphere, the radius of the marble is one-half of the diameter, or width of the marble. Use the formula for volume,V = (4/3) pi r3where pi is approximately 3.1416 and can usually be found on a scientific calculator. R is the radius as mentioned before. The formula in text is "four-thirds times pi times the radius cubed." Make sure to do the cubing first.From the displacement the marble causes in water or other liquidyou can measure the volume of a marble by filling up a glass beaker to whatever amount you'd like,then you would see how much the water went up.and that would be you answerFrom the density of the marbleWeigh the marble and determine typical density of glass from available tables. As the density of the marble is found by the formulaDensity=mass/volume,divide the mass in grams by the density in gm/cm3 to determine the volume in cm3.
There is not enough information to answer the question.
All of the above? You can say the same thing in many ways. All of the following are different ways of saying the same thing, and all are correct: The marble sinks because the marble weighs more that an equivalent volume of water. The marble sinks because its density is greater than the density of water. The marble sinks because it has a greater mass than than same volume of water (and there is gravity/acceleration).
Mass is a meause of density times volume. Therefor, mass= density x volume, and density = mass/volume. You divide 243 into 994. The answer to your question is approximately 4.13 grams per cubic cm.
divide the mass over the volume and the answer is 2.3 D=M over V D=23 over 10=2.3.
Density = Mass/Volume = 3.050/[4/3*pi*r3] = 2.91 grams/cm3
You are supposed to divide the mass by the volume.
