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.
No. That's the beauty of "density". It's a characteristic of the substance, and the size of the sample has no effect on it. As long as the sample is pure, a pinhead of it has the same density as a truckload of it.
Density = Mass/Volume = 57.2g/11 cm3 = 5.2 gcm-3
Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.
The volume is 0,62 L or 6,2 dL.
if u made the piece ofmetal hollow it can float unless its density is larger than the water densityANSWER:If you make it displace more water than what makes it sink, it will float, as in a ships hull. If you make pontoons out of it, it will float. If you make an enclosed shape that contains enough air, it will float. There should be less density in the item than the water.

density is a physical property of the material, it has nothing to do with the size of the piece. lead is 11.35 g/cc iron is 7.874 g/cc steel is between 7.75 and 8.05 depending upon type of steel.
No, a piece of iron will sink in water because its density is greater than that of water.
7.86 grams/cm3===========
The density should be identical regardless of the quantity, because "density" is what's called an intrinsic property; it doesn't matter how much of the substance there is.
The density of the iron piece is calculated by dividing the mass by the volume. In this case, the density would be 2kg / 256 cm^3 = 0.0078 kg/cm^3.
Density = Mass/Volume = 5.6grams/20cm2 = 0.28 g/cm3 This is clearly a hollow piece of iron since the density of solid iron is 7.9 g/cm3
lead is more dense
The density of iron (at room temperature) is approx 7.87 grams/cm3. Therefore, volume of 63.6 grams = 8.08 cm3
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
The density is 7.8 grams per cm^3.
The absense of heat is zero on the Kelvin scale, which is −273.15 degrees Celsius. So 0 C is 273.15 K, and 18 C is 291.15 K. Twice that is 582.3 K, or 309.15 C.
