If I have 10 silver coins and they weigh 55 grams and displace water from 25 mL to 26 mL, what is the density? What is the specific gravity?
Are these 10 coins of the same type?
density = g/mL = 55g/1 mL = ? but this is not the reported density of Ag; therefore, the coins must not be the same.
Is this a made up problem? The density of the heaviest metal in the periodic table is no more than about 20 g/mL or so. The tabulated value for density Ag is 10.1 g/mL.
The specific gravity is the same numerical value as density but no units.
