Verified by Toppr
The specific gravity of a substance is defined as the density of the substance divided by the density of water at 4℃. Therefore, the units of density cancel each other & the term specific gravity becomes dimensionless quantity.
Specific gravity =Density of substance/ Density of water at 4℃
Therefore, both Assertion and Reason are correct and the Reason is the correct explanation of the Assertion.
