Answer :
The specific gravity of an material is defined as the ratio of the density of the material to the density of water then the fraction of ice berg above the surface of water is 1.11ppm.
Specific gravity is defined by ASTM D4439 as the ratio of the density of the material in question to that of the reference material at the specified temperature and pressure conditions.
In practice, this is accomplished by measuring the mass of a unit volume of geosynthetics in a standard laboratory atmosphere and measuring again with the geosynthetics immersed in water. Substances with a specific gravity less than 1 float in water.
Geotextile specific gravity is actually the specific gravity of the polymeric raw material used to make the geotextile. Polyethylene and polypropylene float in the specific gravity range of 0.90 to 0.96, so be careful when working in water.
Fraction of iceberg = 1.025/0.917=1.11ppm
