Solved Examples of Specific Gravity Example 1: Calculate the specific gravity of iron. The question that remains is, "Where can I find . The SG result was only 10.16 , which suggests a silver content closer to .800, The mint spec should be: .900 Ag, .100 Cu. Watch on Step 1. No report of Specific gravity urine decreased is found in people who take Colloidal silver. I've tried to do specific gravity tests on my silver coins. Pure silver has a specific gravity of 10.5 gr/cm^3. Consider two balls of equal weight but of different specific gravity, for instance a 10 gram gold ball and a 10 gram silver ball. Here we test two questionable Chinese silver Pandas (2006 &2011) versus an authentic 2014 Panda using the specific gravity test. Step 5. The remaining 7.5% of the mixture is often copper, zinc, or a mixture of the two. 5.35 .
