Detailed explanation-1: -g/mL so the specific gravity is 1.20.
Detailed explanation-2: -∴ Density in S.I. system =103×0.8=800kg/m3.
Detailed explanation-3: -Calculating Specific Gravity Specific gravity is determined by dividing the density of a material by the density of water at 4 degrees Celsius. For the calculation, the density of the material and that of the water must be expressed in the same units.
Detailed explanation-4: -The specific gravity (density relative to the density of water) of hydrochloric acid solution is 1.18 g/mL. If 13.7 mL of hydrochloric acid solution is taken, then [13.7 mL x (1.18 g/mL) = 16.2 g is the mass of the hydrochloric acid solution.
Detailed explanation-5: -In this case, the relative density of a substance is 0.8. Hence, the substance float in water.
