the specific gravity of pure sulfuric acid is---------> approximately 1.835 g / cm3
the specific gravity of water is -------------------- >1.000 g / cm3.
The electrolyte, that is, the dissolution of sulfuric acid in water, is usually at a rate of 36% acid, so that, in a fully charged element, we can deduce the electrolyte density, is 1.295 g / cm3. (see attached table)
The specific gravity is actually the difference in the weight of water compared to a specific fluid. It is measured with a hydrometer
