In some countries (for instance, in the United States), density is also defined as its weight per unit volume FormulaMathematically: Density = Mass Divided By Volume where:
Different materials usually have different densities, so density is an important concept regarding buoyancy, metal purity and packaging. In some cases density is expressed as the dimensionless quantities specific gravity (SG) or relative density (RD), in which case it is expressed in multiples of the density of some other standard material, usually water or air/gas.

GNU Free Documentation License density? ? Q. could a can of soda with a calculated density of 1 g/ml could have floated? Asked by no pictures please - Mon Dec 22 17:44:18 2008 - - 5 Answers - 0 Comments A. In order to float, the density of an object must be less than that of the liquid around it. If you're asking if the soda can will float in pure water, there are a few possible answers. If the soda inside the can has a density of 1.0 g/mL, then the can would sink because the total density of the aluminum and the soda is greater than that of water. If the density of the can and soda together is 1.0 g/mL, it still wouldn't float. If you dropped the can in water, the inertia would take the can to the bottom and it would remain there since it's the same density as the water. If it were placed in the water with little to no inertia, the can would remain where it was placed assuming there are no other forces acting on it such as a water… [cont.] Answered by Spaghetti Cat - Mon Dec 22 18:13:53 2008 How does the density of the fluid affect the viscosity? Q. When the density of a fluid is increased, how will the viscosity change? And please don't make the answer blatant because we're "not supossed" to know what the answer. So in other words how can we say that an object becomes more viscose with higher density another way? Asked by spunjb - Sun Feb 10 15:20:20 2008 - - 1 Answers - 0 Comments A. The two properties aren't related. Both are constant physical properties of a substance at a specific temperature. If you heat a viscous product like oil, it will expand, decreasing density, and thin out, decreasing viscosity. However, the changes are a result of the temperature change, not of a relationship between viscosity and density. If you consider tert-butanol, water, and methylene chloride, they are listed in order of increasing density,and decreasing viscosity. There is no correlation between the two properties. Answered by Frank the Tank - Sun Feb 10 16:05:44 2008 How do I find the density of sand particles in this question?
Q. An experiment was performed in which an empty 100 mL graduated cylinder was weighed. It was weighed once again after it had been filled to the 10.0 mL mark with dry sand. A 10mL pipet was used to transfer 10.0 mL of methanol to the cylinder. Use the data (below) to find the density of dry sand, the density of methanol, and the density of sand particles. Mass of cylinder plus wet sand 45.2613 g Mass of cylinder plus dry sand 37.3488 g Mass of empty cylinder 22.8317 g Volume of dry sand 10.0 mL Volume of sand + methanol 17.6 mL Volume of methanol 10.00 mL I was able to get the first two densities, but how do you find the density of sand particles? @cattbarf: That seems to me like it would be the way to find the density of dry sand, but… [cont.] Asked by Andrew Z - Sun Jul 29 17:51:42 2007 - - 2 Answers - 0 Comments A. Well, there are spaces between the sand particles ad the fluid occupies these spaces. If I were to use that assumption to calculate the density of sand particles, I'd have to say that the sand particles only occupy a volume of 7.6mL. They weigh the same as the dry particles, so use that mass to calculate the density. However, if sand particles refers to sand+methanol, the use the weight of the wet sand (45.2613-22.8317)g and volume 17.6mL to calculate the density of the sand particles. I'd do both calculations if I were you to be on the safe side.
