Such a substance will float on water, if that's of any help.
500 mg is 1/2 gram. That's less than a gram.
That would depend upon the density of the oil (which will depend upon temperature), how absorbant of oil the substance was and how deep the oil is. Assuming the substance does not absorb any of the oil then depending upon the oil various things would happen: In some oils such as Car oils, Coconut oil, Crude oil California, Linseed oil which all have a density less than 0.95 g/ml the substance would sink (unless the oil was not deep enough in which case the substance would sit on the bottom of the container and appear above the surface of the oil). In other oils such as Castor oil, Crude oil Mexican, Rosin oil which all have a density greater than 0.95g/ml the substance would float.
No. 1 gram is 1,000 milligrams, which our research staff says is more than 750 .
The word is "weigh" not way! In any case, there cannot be an answer because a gram is a measure of mass, not of weight.
For the same mass, yes.
No, density is simply a property of a substance. It's how "heavy" something is. Water, for example, has a density of 1 gram per milliliter. Meaning every milliliter weighs one gram. Some are much more (Mercury), some are much less (Air).
Milligrams versus millilitersOne milliliter of water weighs one gram. There are 1000 milligrams in one gram.One milliliter of other substances will weigh more or less, depending upon their densities. A millilter of gasoline, for example, weighs less, and a milliliter of mercury weighs more -- WAY more. (No pun intended.)Milligram is a unit of mass; milliliter is a unit of volume. You can't directly convert the two. If you know the density of a substance, you can say, for example, "1 milliliter of water has a mass of 1 gram (1000 milligrams)", or "1 milliliter of lead has a mass of about 11 gram".
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.
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.
The density of a solid not completely submerged in water is less than 1 gram per milliliter, the density of water. Only the volume of the submerged portion will displace the water and the portion on floating above the level of water cannot be measured.
the object with less density rises to the top of the object
Density. An object will float in a substance if its density is less than the density of the substance. The density of water is 1 kg /L or 1 g/ cm3. Anything with a density less than this will float.
That indicates that the average density of an egg is greater than the density of pure water but less than that of salt water. Salt water has more density the regular/pure water and the more salt you add the more it floats.
Float
It floats
mass of a substance is constant at any place in the universe.the reason for floating is its density is less than density of medium in which it is floating
The density of water is roughly 1 gram/cm3. If the density of the substance is less than that, then a solid lump of it can float. Otherwise it can't, but you can form the lump into shapes that can float, just as plate steel is formed into the shape of cruise ship or an aircraft carrier.
