Specific Gravity Formula: Calculation, Factors Affecting

So, put the values in the specific gravity equation to know the answer. Specific Gravity = ρobec ρH2O ρ o b j e c t ρ H 2 O = 12g/mL 1g/mL 12 g / m L 1 g / m L = 12. So the density of the object is 12 g/mL and the specific gravity is 12. Hence, the specific gravity is greater than 1 so the object will sink in the water.
