What fraction of the volume of an iceberg (density 917kg/`m^(3)` ) would be visible if the iceberg floats (A) in the ocean (salt water density 1024kg/`m^(3)`) and (B) in a river (fresh water density 1000 kg/`m^(3)` )?(when salt water freezes to form ice, the salt is excluded. So an iceberg could provide fresh water to a community)

Explanation

(a) Fraction of 10 % (b) Fraction of 8.3 %
