Specific Gravity Determination Bottle 10 mL Fashion

The specific gravity bottle is another instrument (other than a hydrometer) used to measure specific gravity at 20 °C.
The bottle is weighed empty, filled with the liquid whose specific gravity is to be found, and then reweighed. The difference in weight is divided by the weight of an equal volume of water to give the specific gravity of the liquid.

The density of water @ 20 °C = 0.99821 g cm³

Wt. Full – Wt. Empty = Specific Gravity
.99821 g cm^{3 x (10 mL)}
