WebMar 14, 2024 · SG might also be used (as Archimedes did) to distinguish pure gold (SG = 19.3) from 14K gold (SG =13.3) or pyrite (SG = 5.1). Some specific gravities of minerals are shown below. Online mineral vendors sell equipment for determining specific gravity, but it is simple to do in the lab. Specific gravity is related to density, but it is unitless. WebStep 7. Match your calculation with the specific gravity to find out the metal purity in the chart below. Once you determine the specific gravity, it is … WebMay 6, 2024 · Consider two balls of equal weight but of different specific gravity, for instance, a 10-gram gold ball and a 10-gram silver ball. The gold ball has an sg of 19.3, while silver has an sg of 10.5. Because gold has an sg that is almost twice as much as silver, you can imagine that the 10-gram gold ball will be smaller than the 10-gram silver … teacherlife
