The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit. When substances dissolve in water, the density of the solution is usually different from pure water. For example, the density of whole blood for humans is ~1.060 g/mL. The density of urine varies in the ...

Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4. Measure or obtain elsewhere the volume of the substance. Convert the volume to the cubic meter unit. If the volume is given in liters, then divide it by 1,000.

3.1.3 Specific Gravity. Iron ore samples I1, I2, and I3 have a specific gravity of (sim ) 4.72, 4.70 and 4.65, respectively. The observation found that the finer ore sample has high specific gravity than the coarser ore sample. Hooper and Welch reported that the coarser particle has less specific gravity than concerning finer particle …

Density: Meteorites are usually quite heavy for their size, since they contain metallic iron and dense minerals. Magnetic: Since most meteorites contain metallic iron, a magnet will often stick to them. For "stony" meteorites, a magnet might not stick, but if you hang the magnet by a string, it will be attracted.
