If a mineral has a specific gravity of 7.0. What does this mean?

Answer 1

It means that the mineral is 7.0 times more dense than water at #4^@C#.

The specific gravity (also called relative density) of a material is a ratio of the density of that material to the density of water at #4^@C#, which is the temperature at which water has its maximum density. Density itself is defined as mass per unit volume : #rho=m/V#.
#thereforeSG=rho_(rel)=(rho_s)/(rho_(water at 4^@C)#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
