Note that "cm" is not a volume, so I'll assume you mean "cm3". 15 / 2 = 7.5 gm/cm3
You cannot. Density = Mass/Volume. You have only volume, no mass and so there is no way to determine density.
No, you can compare densities for objects of different sizes. Just divide mass by volume for each object.
Since density is defined as mass divided by volume, the statement that the 100g piece of iron has twice the density as the 50g piece would only be true if they occupied the same volume. However, since iron is an element, it will not vary so widely in density in solid form. Thus, it is more than likely that they are different volumes with the same density, and only the mass of the first piece is twice the mass of the second.
List a metric unit for each measurement: lenght, volume, weight, and density,
Since density=Mass/volume. If 2 solutions have the same volumes, they would have different densities because their masses are different. More explanations. For example same volume of aluminum and iron would have different mass because the atomic mass of aluminum is comparatively less than that of iron. Aluminium has nearly mass 27 amu where as iron has 56 amu. The crystalline structure would bring the atoms with different lattice distances and so the density would differ. Answer Objects of same volume have different density because as Density is equal to mass over volume so according to this relation volume and density are inverseley propotional to each others so when we increase volume density decrease so two solutions can have same volume and different densities.

mass = volume x density
You just need to rework the density formula: D = M / V, where D is density, M is mass, and V is volume. So all you need to do is put in the Density and Mass and solve for V: D = M / V D * V = M V = M / D And so our volume becomes Mass divided by Density.
Measure the mass and volume of both to determine each's density (mass/volume). If the object is less dense; it will float, if it is mroe dense; it will sink.
mass = volume x density
Density = Mass/Volume, with this equation, if two things are given the third can easily be calculated. In your question, you was volume when density and mass are given. So Volume = Mass/Density
with a mass and a volume
Copper has a density of 8920 kg/m3. So 5kg is 0.000565 m3 or 560.5 cm3.======================================Density of copper (look-up) = 8.920 gm/cm3Definition: Density =mass/volumeMultiply each side of the definition formula by (volume): (Volume) x (Density) = (mass) Divide each side by (Density): Volume = (mass)/(density) Volume = 5,000/8.920 = 560.5 cm3 (rounded)
Density is mass/volume. If you have a sample of calcium, then you can determine its mass and volume. Then divide the mass by the volume. If you don't have a sample of calcium, then you can look it up. Some periodic tables give the density of each element. Also, if you do a search, you will find a Wikipedia article that will tell you the density of calcium, which is 1.55g/cm3. Please refer to the related link below, which is the Wikipedia article on calcium. Wikipedia has wonderful articles on the elements.
If you want to determine if the density is greater than water, the easiest method is to place it in a bath of water. If it floats then its density is less than water. If it sinks it is less dense than water. Very few minerals are less dense than water. The other method is to weight the piece and then determine its volume. Dividing the weight by volume with give the density. The density of water is 1 gram per cubic centimeter. Volume of irregularly shaped items can be determined by filling a cup with water to the very brim. Carefully insert the sample into the cup and collect the displaced water in a pan. Weigh the pan and covert the weight of the water to a volume using the density of water. This gives the volume of the sample since each unit of water has replaced by an identical volume of water in the cup.
