Question

If the density of Aluminium is 2.7g/cm3 and the density of silver is 10.5g/cm3. What are the values of their specific gravities?

Answer 1

Specific gravity is the ratio of the mass of a substance at a given volume and temperature divided by the mass of water at that same volume and temperature..... density is usually measured at 25 deg C, and the density of water at 25 is 1.0g/cm3.
So 2.7gAl/1.0gH2O = 2.7
and 10.5gAg/1.0gH2O = 10.5

Answer 2

S.G. of Al=2.7 and S.G. of Ag=10.5
